    Description
The CMS ECAL is a hermetic, fine grained and homogeneous calorimeter containing 75848 lead-tungstate (PbWO₄) crystals, located inside the CMS superconducting solenoidal magnet. The scintillation light is detected by avalanche photodiodes (APDs) in the barrel section and by vacuum phototriodes (VPTs) in the two endcap sections. A silicon/lead pre-shower detector is installed in front of the endcaps.
Presented is ECAL performance and upgrade plans.
