iseg PHQ modules are developed for a direct HV supply of modern photo multiplier tubes (PMT) with the high voltage power supply integrated in the PMT socket. Advantages of PMTintegrated power supplies are:
no HV cabling or connectors necessaryno separate HV supply neededsmall form factorincrease of reliabilitypower dissipation reduced by factor 10 and morehigh temperature stability and thermal balance
DC/DC HV supply compactly integrated in PMT socket
low ripple and noise, low EMI
low power consumption
high linearity even at high pulse load and rates by stabilized dynode voltages
