C8728 is a DP type socket assembly for 28 mm(1-1/8 inch)
diameter side-on photomultiplier tubes, incorporating a
regulated high voltage power supply and an active voltage
divider. It enables simple and stable PMT operations with
extended DC output linearity by only supplying +15 V and
connecting a high voltage control voltage of 0 V to +3.6 V.
