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.
