Minutes for UCL Proton Calorimetry Meeting, 29th August 2018 (D12, Physics & Astronomy, UCL)


Matthieu Hentz, Simon Jolly, Saad Shaikh


  • Running simulations to improve pCT image reconstruction using Simon Rit's code:
    • Reasonably sure Simon used 4*10^10 protons for reconstruction.
    • Corresponds to 900 per mm^2 per projection with 720 projections.
    • 56.25 million protons per projection.
    • Using 2.5 million per projection took more than 2 days...
  • To Do:
    • Investigate use of UCL Legion/Myriad cluster to simulate much larger proton numbers.
    • Rebuild phantom in pure GEANT4 to remove need for GATE.


  • Currently refining code for waveform reconstruction:
    • Building GUI in ROOT.
    • PRaVDA tracker code for reading out hits obtained from Dan Walker.
  • Will plan a visit to Birmingham from late September onwards.
  • To Do:
    • Familiarise with PRaVDA tracker reconstruction code.
