Minutes for UCL Proton Calorimetry Meetings, 12th April

Saad Shaikh, Simon Jolly, Raffaella Radogna

Tested Rev. C boards at home again with a torch – all looks OK.
- Will give Marko thumbs up to produce further boards.
Simulation now can do Bortfeld fit on simulated depth-dose curve.
Met with Laurent and Raffy to discuss simulation physics lists, optical properties and light collection.
- G4 v11 only requires simple implementation of QBBC physics list, replacing EM physics with option 4 and registering optical physics.
- Material composition, scintillation slow and fast components, ratio, yield etc. are consistent across Laurent's and Jeremy's simulations
- Optical properties (photon energy spectrum, absorption spectrum and wavelength shifting) seems to have been passed down from G4 examples(?) -> LZ -> Anastasia -> Laurent. Unclear whether figures are correct or even really matter. Will need to investigate this further down the line.
Next step for simulation is to implement photon counting by sheet.
Simon has printed new scintillator stack holder with gaps for fibre LEDs. Will begin testing new prototype after Easter break.
