Experiment Plan

  • Background & calibration shoot-throughs (background at all 8 DDC232 full-scale ranges)
  • Pencil beams, 70-110 MeV, 5 MeV steps, 2 currents (high/low)
  • Live fit demo: pencil beam 100-110 MeV
  • Treatment plan: range steps, 110 MeV-70 MeV, 1 MeV steps, no x-y scanning (demo live fit)
  • ±1, 2, 3, 4mm in x-y planes, 100 MeV
  • Detector misalignment, ±2°, ±5°, ±10° 100 MeV
