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

Present

Simon Jolly, Ruben Saakyan, Anastasia Basharina-Freshville, Matthieu Hentz, Jordan Silverman, Dan Walker, Laurent Kelleter

DW:

• Had discussions with Tony Price (+Mariana) at Birmingham:
  • Marian has extracted timestamps for tracker data.
  • Should be able to match up events from scope with tracker events.
  • Now having to deal bugs in tracker reconstruction code...
• Tony Price confirms an energy of 28 +/- 0.15 MeV.
• RS suggests broad energy spread may be a result of upstream tracker degrading the beam.
• To Do:
  • Fix bugs in tracker reconstruction code.
  • Correlate with scintillator pulses.
  • Create 3D dose distribution.

JS:

• CAD models of Clatterbridge beamline now complete based on MH's models:
  • Some material definitions not clear: Kapton needs clarifying.
• MH suggests including the collimator and cap inside the nozzle.
• To Do:
  • Add collimator and cap.
  • Rerun simulations to check differences in simulations with CAD components.

MH:

• Finished coursework: 7 weeks till next one.
• Writing documentation for simulation: tidying up macros for publication.

LK:

• ISDI sensor now working with DAQ PC:
  • XCAP-Lite software runs under Windows 10.
  • Can see ambient light but not light from LEDs.
