Proton Calorimetry/Meetings/2024/07/24
Minutes for UCL Proton Beam Therapy Group Meetings, 24th July
Present
Joe Bateman, Simon Jolly, Sonia Escribano, Febian
Simon Jolly
- Sonia, Joe and Simon to visit to Maastricht Proton Therapy Centre on 13th and 14th August.
Febian
- Working on first FPGA tasks
- Contact Matt to check things such as generating clock signals etc.
- No more CDT projects until industrial placement - ideally sooner rather than later e.g. Jan
Joe Bateman
- Successfully ran first Geant4 B1 basic example (from https://ep-dep-sft.web.cern.ch/geant4-usage-cern) over HEP cluster using CVFMS Geant4 11.2 gcc-10 installation.
- Next step to look at visualisation - i.e. what packages need to be sourced/installed.
Sonia Escribano
- Run59 and Run60 5x5 box field 5 Gy from UCLH Beam Test
- Strange response beyond distal edge of Bragg peak - potentially due to calibration or other issue
- Ratio between photodiode response for run 59 and 60 constant for most photodiodes except between ~150 and 168 mm
- acquisition on run starting too late and snipped energy layer at the start
- with have better data would be interesting to produce time integrated measurements of calibrated measurements to compare to beam current
- Within each group - integrated depth light output should be the same between each run - way to check photodiode reproducibility between run 59 and 60 since same beam parameters delivered
- Check dicom to check number of energy layers
- GUI improvements
- Beam energy and range buttons on visible when fit gives good results
- Can run without specifying number of measurements - set a default of 1.5 mins
- No longer showing graph from prev. Measurements when press graph if not connected
- How to stop replay GUI - will discuss with Simon
