# Scintillator stack holder redesign
# Scintillator machining
# Peli case scintillator module holder frame
# SciFi frame and holder
# Kria and carrier board installation in Peli 1510 case
# Alignment frame
# Cover/Alignment plates and markings
# Nozzle mount

'''Items 1–5 to be completed by end of May'''

=== Redesigned scintillator stack holders ===

* Moving from 2-sided to 4-sided readout
* Sheet thickness reduced from 3mm to 2.5mm
* Updating photodiodes from [https://www.hamamatsu.com/eu/en/product/optical-sensors/photodiodes/si-photodiodes/S12915-16R.html S12915-16R] single element photodiodes to [https://www.hamamatsu.com/eu/en/product/optical-sensors/photodiodes/si-photodiode-array/si-photodiode-array/S12362-021.html S12362-021] 16-element arrays.
* New DDC boards are H-shaped to accommodate updated USB-C cable routing and 4-sided photodiode arrays.
* Redesigned stack holders need to accommodate thinner scintillator sheets — and therefore a reduction in stack thickness from ≥96mm to ≥80mm — with identical transverse dimensions of 100mm x 100mm.

=== Scintillator machining ===

* Scintillator thickness needs to be reduced from 3mm to 2.5mm to accommodate photodiode spacing in new arrays.
* Injection moulded sheets do not have parallel large faces.
* Lower quality “opaque” sheets need surface finishing improved.
* Machine '''all''' sheets down to 2.5mm for new stacks.

=== Modifications to Peli 1510 case after Prague/UCLH ===

Order of priority:

# Wheel holders. > Designing
# Lowered scintillator stack rail cross braces to reduce stack height to match alignment plates. > sent to workshop, it should lower the stack by 5mm
# End face studs to allow Peli case to stand vertically. > will do once wheel holder are done
# Lid rails for electronics. > not started
# Alignment plate positioning.
# Prague nozzle mount

Aim for 1–4 in time for Trento beam test commencing '''28th September'''.

==== Wheels & Mobility (Zarges) ====

===== Redesign Wheel Fitting Mechanism =====

* The current bolt/axle slot is poorly suited for removal (too big/shallow).
* Explore improved methods for wheel installation, removal, and securement.

===== Wheel Holders =====

* Wheel holders from the Zarges case are currently located on my desk.
* Redesign and reprint parts to fit beneath the Peli case and support the Zarges mechanism.

==== Peli Case Modifications ====

===== Alignment Plates =====

* Alignment plates appear to sit at different heights, possibly due to misaligned bolt holes.
* The issue may be caused by new wheel holder prints making one side sit higher.
* Investigate options:
*# Redrill bolt holes
*# Create wider plates to match the Peli case lip
*# Design improved alignment plates

===== Box Markings =====

* Add markings on the case to align with cover plate positions.
* Intended to ease module removal and reinstallation.
* Note: This is challenging with the Peli case design.

==== Thermal & Mechanical Concerns ====

===== Raspberry Pi Heat =====

* The case exhibits poor airflow.
* Consider adding ventilation while maintaining:
*# Light-tightness
*# Structural integrity

===== Module Height & Pi Proximity =====

* Module 4 is too close to the Raspberry Pi and was warm after the beam test.
* Redesign crossbars to:
*# Lower the overall stack height
*# Improve thermal spacing

=== Nozzle mount for detector enclosure ===

* Small Peli case needs to be nozzle-mounted for beam tests.
* '''SJ''' in contact with Prague/IBA for mounting points for Prague-IBA nozzle.
* Dimensions already obtained from UCLH measurements:
** '''SJ''' has contacted UCLH to check whether we can bypass light curtain.
** Assume we can't and design to bypass mechanically...
* 3 parts needed:
*# Nozzle mounting plate that sits inside nozzle using range modulator plate mounting slots.
*# U-bracket that slots in to this mounting plate — bypassing the light curtain — with a 40 x 30 cm hole for the beam to pass through.
*# Peli Case support that fixes to the U-bracket and holds the Peli Case whilst gantry is rotating.

=== New scintillator stack holders ===

# Stack holders 3D printed: remake by hand if time allows.
# Mounting plate to screw to Thorlabs optical breadboards in Peli cases:
#* Rough version already 3D printed.
#* Needs modifying to fix stack holder in place with M14(?) nuts.
#* Must be able to mount upside down.
# New frame needed for patch panel with 50mm stand off to allow deeper connectors not to interfere with scintillator stacks.

==== Holder for NPL Transmission Calorimeter ====

* TC needs to mount into Peli Case in front of stack holders.
* CAD STEP-files already received from Sam Flynn (NPL) for existing holder.
* If making new holder, exit pipe for electronics cabling needs to be shortened to fit in small Peli case.
* If making holder for holder, must mount to Thorlabs optical breadboard (M6 holes on 25mm pitch?).
* Centre of holder must be '''71 mm''' from baseplate (scintillator stacks are 50mm radius, plus 21mm offset from base).

==== Holder for Birmingham Pixel Sensor ====

'''Unlikely this will ever be needed'''

* '''Tony Price''' (Birmingham) has provided dimensions to '''HB'''.
* Holder needed to support pixel sensor between TC and scintillators.
* Peli case needs 100x10mm slot cut to left of side handle to allow sensor ribbon cable to pass through.

=== Scintillator Machining ===

# '''Bari scintillating fibre holder:'''
#* Bari are designing the scintillating fibre assembly for the '''QuADProBe'''.
#* Prototype fibre array holder machined from aluminium.
#* Clinical prototype ideally needs a version in plastic.
#* Review Bari CAD drawings and recommend suitable materials.
# '''Scintillator machining:'''
#* Promising results from Datron: chase up potential workshops who could machine scintillator for us.
#* Liaise with '''Martin Blackman''' in main workshop to assess quality of his scintillator machining.
#* Write case and obtain quote for us to purchase Datron Neo.

* Dimensions already obtained from UCLH measurements:
** '''SJ''' has contacted UCLH to check whether we can bypass light curtain.
** Assume we can't and design to bypass mechanically...
* 3 parts needed:
*# Nozzle mounting plate that sits inside nozzle using range modulator plate mounting slots.
*# U-bracket that slots in to this mounting plate — bypassing the light curtain — with a 40 x 30 cm hole for the beam to pass through.
*# Peli Case support that fixes to the U-bracket and holds the Peli Case whilst gantry is rotating.

=== New scintillator stack holders ===

# Stack holders 3D printed: remake by hand if time allows.
# Mounting plate to screw to Thorlabs optical breadboards in Peli cases:
#* Rough version already 3D printed.
#* Needs modifying to fix stack holder in place with M14(?) nuts.
#* Must be able to mount upside down.
# New frame needed for patch panel with 50mm stand off to allow deeper connectors not to interfere with scintillator stacks.

==== Holder for NPL Transmission Calorimeter ====

* TC needs to mount into Peli Case in front of stack holders.
* CAD STEP-files already received from Sam Flynn (NPL) for existing holder.
* If making new holder, exit pipe for electronics cabling needs to be shortened to fit in small Peli case.
* If making holder for holder, must mount to Thorlabs optical breadboard (M6 holes on 25mm pitch?).
* Centre of holder must be '''71 mm''' from baseplate (scintillator stacks are 50mm radius, plus 21mm offset from base).

==== Holder for Birmingham Pixel Sensor ====

'''Unlikely this will ever be needed'''

* '''Tony Price''' (Birmingham) has provided dimensions to '''HB'''.
* Holder needed to support pixel sensor between TC and scintillators.
* Peli case needs 100x10mm slot cut to left of side handle to allow sensor ribbon cable to pass through.

=== Scintillator Machining ===

# '''Bari scintillating fibre holder:'''
#* Bari are designing the scintillating fibre assembly for the '''QuADProBe'''.
#* Prototype fibre array holder machined from aluminium.
#* Clinical prototype ideally needs a version in plastic.
#* Review Bari CAD drawings and recommend suitable materials.
# '''Scintillator machining:'''
#* Promising results from Datron: chase up potential workshops who could machine scintillator for us.
#* Liaise with '''Martin Blackman''' in main workshop to assess quality of his scintillator machining.
#* Write case and obtain quote for us to purchase Datron Neo.

== Welcome to the UCL High Energy Physics Group Proton Beam Therapy Wiki. ==

This contains information on the various proton therapy-related experiments and software in use by the UCL [http://www.hep.ucl.ac.uk/pbt/ High Energy Physics] and [http://www.ucl.ac.uk/medphys/research/protons Proton and Advanced RadioTherapy (PART)] research groups.

== [[Software|Software and Simulations]] ==

The initial purpose of this Wiki was to make the setup and use of software used for proton therapy-related simulations easier for less experience users, primarily the [[Software/Geant4|Geant4 simulation package]].

The following software is available for use on the [[Software/Geant4/UCL HEP Cluster|UCL HEP Linux Cluster]]:

* [[Software/Geant4|Geant4]]. Geant4 is a toolkit for the simulation of the passage of particles through matter. Its areas of application include high energy, nuclear and accelerator physics, as well as studies in medical and space science.

* [[Software/ROOT|ROOT]]. ROOT is a modular scientific software framework. It provides all the functionalities needed to deal with big data processing, statistical analysis, visualisation and storage. It is used for the analysis of data produced with the Monte Carlo simulations packages described above.
* [[Software/BDSIM|BDSIM]]. BDSIM is a Geant4 extension toolkit for simulation of particle transport in accelerator beamlines. It allows an accelerator to be described by text input file and Geant4 geometry is automatically created based on libraries of generic components. It provides fast in-vacuum thick-lens tracking as well as the full physics processes of Geant4.
* [[Software/TOPAS|TOPAS]]. TOPAS is a Geant4 extension toolkit for Monte Carlo simulation of medical physics applications. It allows radiotherapy and imaging systems to be described by text parameter files and automatically creates Geant4 geometry from pre-built component libraries. Originally developed for proton therapy, it provides extensively benchmarked and experimentally validated simulations with systematic validation against clinical measurements for passive scattering and pencil beam scanning systems.

More details of the available software can be found on the [[Software|PBTWiki Software page]].

== Research ==

UCL runs a number of research projects related to proton therapy. Most of these are described in more detail on the [http://www.ucl.ac.uk/medphys/research/protons Proton and Advanced RadioTherapy (PART) research group page].

More detailed information is available on the following research projects:

* [[Proton Calorimetry|Quality Assurance Range Calorimeter (QuARC)]]: Development of a fast, accurate scintillator range telescope for high resolution proton energy measurements.
* [[Clatterbridge|Clatterbridge Simulations]]: Simulations of the beamline for the 60MeV ocular proton therapy beam at the Clatterbridge Cancer Centre.
* [[Radiotherapy|QA For Radiotherapy]]: Quality Assurance measurements for radiotherapy PDD and Output Factor measurements using plastic scintillator.
* [[Quality Assurance|Quality Assurance]]: A summary of existing systems used for machine and patient QA in clinical proton therapy facilities.
* [[Plasma Wakefield|Plasma Wakefield Acceleration]]: Simulations of the proton driven plasma wakefield experiment, AWAKE.

An [[Photo Archive|Archive of Photos]] taken at various facilities during experimental runs is also available.

== [[Background]] ==

For information on the background to proton beam therapy treatment and research at UCL, please see the [[Background|Background Information page]].

A useful table of [[Proton ranges|proton ranges for clinical energies]] is also available.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==
For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==
For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==
For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==
For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==
For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==
For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==
For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==
For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==
For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==
For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==
For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==
For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==
For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

== Experiment Plan ==
For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.
