Test and preparation of the GE1/1 Low Voltage System

As the collider experiments in high energy physics go towards higher energies and luminosity, the CMS collaboration is upgrading the muon forward region which is particularly affected by the high luminosity. The proposal for the upgrade of the CMS muon forward system involves Gas Electron Multiplier (GEM) detectors to be installed during the second LHC Long Shutdown (LS2), which can handle the extreme particle rates expected in this region along with a high spatial resolution. In this report, the test and preparation of the low voltage system that will power GEM electronics in the CMS experiment are described.
