Minutes for UCL Proton Calorimetry Meeting, 7th March 2018 (D17, Physics & Astronomy, UCL)


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


  • 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.


  • 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.


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


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