Minutes for UCL Proton Beam Therapy Group Meetings, 29th January

Present

Joe Bateman, Sonia Escribano, Simon Jolly, Febian , Raffaella Radogna (via Teams)

Febian

  • First part of presentation on understanding of PBT, the QuARC and associated electronics

Raffaella Radogna

  • Few discussions in Bari about updated design
  • Harry needs to invite Raffy to fusion hub CAD

Sonia Escribano

  • Scintillators
    • 175 sheets have been sent to Wayne and John for machining
    • Now have 183 sheets left in lab
    • In future will need 32 x1.5mm sheets for clatterbridge but will require new ddc board with PD's interleaved
    • Therefore can use some of the left scintillators for this module potentially? So box up left over scintillator sheets
  • Photodiodes:
    • Currently have 192 in use - need 256 for 4 modules
    • Joe has quote for 100
    • Smoke coming from clatterbridge rev b board when testing
      • Something coming into the LDO has blown
    • Need to check polarity of PDs on revB boards
    • PDs on revD boards work except 1
    • USB104 2 working, 1 is not programmed, 4th board that was Febian working with is now working
    • Board4 no longer resetting but when trying to acquire data and cable is in PMODA it doesn't ready any measurements
  • All calibration errors have now been fixed
  • Just have a new file that calculates a file of the scaling factors per PD boards i.e. one file of scaling factors per PD board
  • For calibration files - reversing not necessary as doing shoot through from both sides
  • Would be good for own analysis to have one file for each side
    • 1 hex file
    • 2 calibrated files
    • 2 fitted files

Joe Bateman

  • Fixed discrepancy between TOPAS and FRED Bragg peak for 154.97 MeV pencil beam (due to differences between energy spread definition in the codes).
  • Improved agreement between two simulation codes seen now, although discrepancies increase as energy of PB decreases.
  • Plotted 2D profiles and SOBP for QuADProBe and DICOM param for run33 in TOPAS and FRED
  • Plotted 2D profiles and SOBP for DICOM params in TOPAS and FRED for 3by3 and 5by5 10 Gy box fields - although fields look smeared out
    • ICOM beam size is at isocentre - not at source so need to back project somehow
  • Planning QuADpProBe paper for Frontiers special edition
