== Experiment Plan ==
'''Rev. B Prototype'''
*Background & calibration shoot-throughs (background at all 8 DDC232 full-scale ranges – likely 12.5 pC is most appropriate FSR)
*Pencil beams, 70-130 MeV, 10 MeV steps, in both directions into stack. For direction with Bragg peak in clear sheets, test 2 currents (high/low)
'''Rev. C Prototype'''
*Background & calibration shoot-throughs (12.5 pC FSR)
*Pencil beams, 70-110 MeV, 5 MeV steps, at clinical current.
== Experiment Notes ==
Range calorimeter measurements with CMOS sensor + photodiodes.
