The H7680/-01 PMT modules are capable of high-speed, high-repetition ga-
ted operation. An optimum design in the combination of circuit and photomul-
tiplier tube delivers excellent gating characteristics including a minimum gate
width of 30 ns (H7680-01), 100 kHz repetition rate, and a gate extinction ratio
of 10
7
. The H7680/-01 can operate on a low +15 V supply because of incor-
porating high-voltage power suppy circuit. And, the incorporated PMT gain
can be controled by adjusting the control voltage between +2 V to +5 V.
