NOTE: AThe discrimination level is set at one forth the average electron pulse height to measure the background.
BPlateau voltage (V0) at the test up in HPK.
CThe rise time is the time of the output pulse to rise from 10 % to 90 % of peak amplitude when the entire photocathode is illuminated by a
delta function light pulse.
