Proton Calorimetry/Meetings/2024/12/11

Minutes for UCL Proton Beam Therapy Group Meetings, 11th December

Joe Bateman, Sonia Escribano, Febian, Simon Jolly, Raffaella Radogna (via zoom)

Made list on wiki for components inside peli case etc
We need 256 photodiodes
Do an inventory of all the photodiodes
Rev e boards on their way - small chance could test them before xmas
Potential to mount raspberry pi on lid
Have at least 2 raspberry pi's and mount them both in case they have any issues
Do same with usb 104 so effectively have two parallel machines - one external power supply should be fine
Need to test power supply for cmod board - whether can be powered by external power supply and fpga
Started inventory of all scintillator sheets
Will do same with boards and photodiodes
All gui versions on github

TOPAS installed and working on Plus1 using Geant4 CVMFS installation.
Simulating pb1 from UCLH run33 (SOBP) on TOPAS (over batch farm) and FRED (ran locally) to compare range and beam sizes (at 1cm and r80)
Full 34 pb 3D dose reconstruction of UCLH run33 in FRED using CMOS size, position, intensity and QuARC energies.
- Simulation does not result in smooth SOBP plateau - assuming it's due to CMOS intensity measurements
Will run a comparative FRED simulation using intensities from DICOM instead and another using all parameters from DICOM

Presented further updates to ZMOD daughter board #2
On fpga - looking at using external files for fpga fitting
Have to hardcode data in to fpga
Time analysis - implementing linear regression fitting on fpga - limited resources for data disk space and fitting
