In short, miniHV is a high voltage power supply that is specially designed for use with gaseous detectors. In this respect it can provide and measure output currents in the nA region until 5 microA at a negative voltage range from -3 to -1000 V. In addition the unit offers a sophisticated voltage ramping scheme (linear, followed by an exponential approach to the target voltage) ranging from less than a second to many hours. The unit is exclusively remote controlled using the CANopen A standalone program to configure and control up to 4 units is available.

The full miniHV supply system shown below consists of up to 10 HV units daisy chained to a single power supply unit. Both the CAN signals and the supply voltages are provided by an Ethernet type cable. The power supply unit accepts line voltages from 85 to 264VAC at 47 - 440 Hz.

Presently we intend to develop miniHV units with an extended range up to -5000V. In addition we may consider developing other special miniHV units at sufficient interest:

  • units having a positive range (+3 to +1000 V)
  • units with 4 outputs for GEM applications, output voltage selectable in steps of ~ 50 V by kind of mini banana plugs to different stages of the Cockcroft Walton chain. The overall voltage can still be adjusted with a high resolution.
