  High Voltage system for triple GEM CMS detector.

The prototype of HV system for supply triple GEM detectors is designed. It is consist of two modules - primary HV power supply and HV Distribution Board(DB). The primary HV voltage supply service high voltage for few DB modules.

Each DB work out 7 negative HV levels to powering of 7 electrodes triple GEM detector. Up to 10 independent GEM segments can be supplied from single DB.
