Detector Equipment

  • Stack A:
  • Stack B:
  • DAQ using ** FPGA and Raspberry Pi (running web GUI).


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.
