Experiment Plan

Day 1 (25/10/22) – estimated first beam: 23.00.

  1. Set up mains cabling and networking in treatment and control rooms.
  2. Install Peli case on treatment couch.
  3. Calibration shoot-through measurements of 4 rev. D modules: either rotating case or modules for back shoot-through.
  4. Pristine Bragg peak measurements at clinical current for full clinical range.
  5. FLASH measurements at 245 MeV.

Day 2 (26/10/22) – estimated first beam: 23.00.

  1. Set up PeakFinder
  2. WET Measurements for each of the 4 rev. D modules.
  3. Single scintillator/mylar foil removal experiment with Peakfinder.
