==== Single module ====
 
All tests with Helium.


Single module
# 30mm thick scintillator sheet: check max signal height and replace with black wrapped sheet if signal too large. 22mm Helium range so Bragg peak fully contained in scintillator.
# Increase rate from kHz up to MHz to identify maximum safe particle rate. Observe effect of PMT current saturation.
# Increase Helium energy from 22mm up to ~260mm in 10mm range steps.
# 1mm range steps from 22mm to 32mm.
# 1mm range steps from 190mm to 200mm.
# Investigate effect of upstream degrader material.

    5. Repeat measurements with 50mm PMMA sheets until Helium SOBP fully contained in detector.
    6. Add 30mm PMMA sheet and repeat Helium measurements in small transverse steps (tumour motion simulation).

Single module

All tests with Helium.

  1. 30mm thick scintillator sheet: check max signal height and replace with black wrapped sheet if signal too large. 22mm Helium range so Bragg peak fully contained in scintillator.
  2. Increase rate from kHz up to MHz to identify maximum safe particle rate. Observe effect of PMT current saturation.
  3. Increase Helium energy from 22mm up to ~260mm in 10mm range steps.
  4. 1mm range steps from 22mm to 32mm.
  5. 1mm range steps from 190mm to 200mm.
  6. Investigate effect of upstream degrader material.
