Minutes for UCL Proton Calorimetry Meeting, 14th November 2018 (D17, Physics & Astronomy, UCL)

Present

Simon Jolly, Raffaella Radogna, Laurent Kelleter, Jeremy Ocampo, Saad Shaikh, Fernando Franco Felix, James Golbourn

RR:

  • Working through preliminary documents for patent application for Vassilios Albanis.
  • Started testing new PCIe Thunderbolt enclosure for CameraLink card.
  • Designed a logo!
  • To Do:
    • Organise equipment in new boxes.
    • Get PCIe enclosure working.
    • Start learning analysis with Laurent.

LK

  • Working on stuff.
  • Heidelberg data stored on plus1 and relevant parts sent to Lennart Volz.
  • Started looking into Heidelberg data:
    • Rough reconstruction of SOBP.
    • Seeing droop due to high quenching of light.
  • To Do:
    • PTCOG abstracts and registration.
    • Detailed data analysis for Heidelberg data.
    • Prepare for school talk on 4/11/18.
    • Workshop on paper writing 7/11/18.
    • Start writing paper on proton calorimetry results.
    • Analyse Heidelberg beam mixing data.

JO:

  • Been reading background on particle-matter interactions and Monte Carlo simulations.
  • Spoken to Adam Gibson about importing more sophisticated geometries and input beam distributions.
  • Still going through reading list provided by Jamie McClelland and Adam Gibson.
  • To Do:
    • Build Geant4 simulations of Cherenkov emission in water and scintillation light output from scintillator block.
    • Clarify meaning of phase space in radiotherapy.

JG

  • Written project outline for SJ to review.
  • Waiting on SJ to make contact with UCLH QA experts.
  • To Do:
    • Search for more information on QA techniques..
    • Follow up references from PSI paper.

SS:

  • Made progress on reconstructing energy spectra from LeCroy waveform data from Birmingham experimental runs:
    • Modified baseline subtraction now finds peak of pulse.
    • Resulting spectra look very similar to Caen ADC spectra.
  • To Do:
    • Check total number of protons in each peak for eyepatch data.
    • Send spectra to Tony Price.
    • Retrieve tracker data from Tony Price.

MH:

  • Improvements to Geant4 simulations.
  • Reconstruction much faster due to analytical reconstruction algorithm: helps to prototype simulations.
  • Full reconstruction now working: simple phantom gives very accurate reconstruction with fan beam.
  • Looked into labelling individual protons: ROOT truncates strings...
  • To Do:
    • Transfer report almost finished: due Friday...
    • Set up large scale simulations on plus1.
    • Contact Simon Rit and Niels Krah to convert ITK images to DICOM.
    • Contact Jamie McClelland for DICOM image conversion and reconstruction tools.
    • Assign ID to each proton to speed up pre and post matching.
