hvBase: PMT High-Voltage Supply

hvBase: A plug-on HV module for PMT

The hvBase is a low-power high voltage generator for photomultiplier tubes (PMT). It plugs directly onto the PMT and includes the generator and an active HV divider to power the dynodes.
The hvBase can deliver 50 µA DC current and 10 mA pulse current to the PMT anode while maintaining excellent gain stability. At the same time, the unit will only use 20 mA @ 3.3V supply voltage.
The device can can be powered and controlled from a Morpho MCA using analog or digital communication.
The device is sealed and specified over a temperature range of -15°C to +60°C.
