Reconstructing UCLH 04-5/2024 QuADProBe Beam Test Dose Distributions - mainly SOBP and 3x3x7 cm^3 box field using TOPAS (via CVMFS on HEP Cluster) and FRED (locally for now, but eventually over Hypatia GPU cluster).
Disagreement between depth dose curve for FRED and TOPAS (using default physics settings) - agreement in plateau but FRED has sharper and higher Bragg Peak
- Only an issue when there's an energy spread in the pencil beam (i.e. PDD's agree almost perfectly for a mono energetic beam with no spread) - likely to do with energy straggling?
Investigating physics lists and in touch with Maestro o attempt to solve discrepancy (currently taking TOPAS as ground truth)

Consider potential ways of calibrating fibre to PD coupling.
- Using Geant4 sim?
- Scanning diode or uniform light source?
Hassle Simon about Hamamatsu PD arrays !!!
Prepare slides about DAQ systems for existing fibre / fibre array detectors

PTCOG - decided not to submit for standard but possibility of late breaking if have beam test beforehand
PPRIG - submitted
