Saad Shaikh

• 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.
• Awarded £800 from MAPS faculty to fund travel to CALOR conference.
