The C9773 is a high voltage power supply socket assembly for 25 mm (1") diameter head-on photomultiplier tubes (PMT), incorporat-
ing a regulated high voltage power supply and an active voltage divider.
It enables simple yet stable PMT operations with extended DC output linearity by only supplying +15 V and connecting to a potenti-
ometer or a 0 V to +5 V for high voltage adjustments.
