Minutes for UCL Proton Beam Therapy Group Meetings, 6th May

Present

Joe Bateman, Sonia Escribano, Raffaella Radogna (via Teams), Tony Price (via teams), Simon Jolly

Simon Jolly

• For frontiers paper from Tony we need:
  • Individual frame with single clear spot
  • Individual frame with two blurred spots i.e. catching spot moving
  • Frame that just shows corrupted data
  • Summed data for one layer - all as pictures just for 5by5
  • Single frame from gantry 1 on first night compared to egg shaped from gantry 3

Raffaella Radogna

• Approved for 7 hours beam time in Trento - likely also includes setup etc

• Going to Rome to investigate gluing together square fibres

Sonia Escribano

• Overall light output from individually calibrated modules differs between modules - is it better to calibrate overall stack or individual modules and then scale?
  • Calibrate photodiode by photodiode I.e. divide by individual photodiode values
• Calibration is giving values too high for some of the modules which is making high energy Bragg peaks
• Dismantle module 4 and reassemble without injection moulded sheet

Joe Bateman

• Continuing with QuADProBe frontiers paper
