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).

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.
