    keyword=Compton electron detector bias voltage calibration

    DAC Output in V
    0 -0.01
    10 -5
    20 -10
    40 -20
    80 -40
    100 -50
    150 -75
    200 -98.2
    255 -101.4

    Calibration is exactly -0.5 per DAC unit. Michel put a diode to limit the
    voltage at less than -100 V
