摘要：

The Compact Muon Solenoid is one of two generic detectors currently being constructed for the Large Hadron Collider at CERN foreseen to begin data taking in 2007. The electromagnetic calorimeter consists of a barrel and endcaps made of PbWO4 scintillating crystals. In the barrel, the scintillation signal is read out by Hamamatsu avalanche photodiodes, connected in parallel in a structure called a "capsule", one for each of the 61200 channels. We present the calibration results and performance statistics obtained for more than 5000 production capsules. (C) 2003 Elsevier Science B.V. All rights reserved.
