The CMS ECAL Barrel HV system
The CMS electro-magnetic calorimeter comprises 75848 scintillating lead tungstate crystals. 61200 crystals are contained in the ECAL Barrel section and these are readout by avalanche photodiodes (APD) with internal gain. The APD gain strongly depends on the bias voltage that, for a gain G=50, is aro...
