Detector Equipment

  • Stack A: 14 clear sheets of scintillator around 2.86 mm thick, with mylar foil for optical isolation, in C-section stack holder and coupled to single Rev. B DDC232 board.
  • Stack B: 11 clear sheets and 3 white painted sheets of scintillator with mylar foil for optical isolation (clear sheets), in C-section stack holder and coupled to single Rev. B DDC232 board.
  • DAQ using USB104 A7 FPGA and Raspberry Pi (running web GUI).

Average thickness: 2.814 mm Stack thickness (excluding mylar): 39.4 mm Stack thickness (including mylar): 39.9 mm

Experiment Plan

  • 60 MeV pristine Bragg peak measurements (and with some absorber for different ranges?):
    • Stack A front and back.
    • Stack B front and back(?)
  • SOBP measurements (one type only?):
    • Stack A front and back.
    • Stack B front and back(?)


Experiment Notes

Stack A + NUC PC.

Beam current nominally 1nA.

Range in eye tissue of 60MeV: 29.3mm

Degrader WET given in eye tissue water equivalent thickness. Multiply degrader WET by 1.05 to get actual WET.

For modulator measurements, Range is 29.3mm minus degrader. Modulation is eye tissue WET difference between Range and minimum range.
