Experiment Plan

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.

  • Set up mains cabling and networking in treatment and control rooms.
    • no beam
  • Install Peli case on treatment couch.
    • no beam
  • Background
    • no beam
  • Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
    • 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
    • additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
    • 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
    • additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
  • Pristine Bragg peak measurements at clinical current for full clinical range:
    • 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
  • Pristine Bragg peak measurements at FLASH current for full clinical range:
    • 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
      • if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
  • Spot scanning:
    • pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
      • 4 beam deliveries per energy


Calibration conventional and FLASH

DDC232 FSR should be determined at max beam current starting from minimum FSR value that does not give signal saturation. This could require 2 or 3 beam deliveries.
