To Do

MC Simulations

Dose Reconstruction

  • 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)

QuARC & QuADProBe Geant4 Simulations

Fibres
