摘要：
The endcap calorimeter of the CMD-2 detector for the VEPP-2M collider is described. The calorimeter consists of 680 EGO crystals, arranged in two endcaps. The light readout is performed by vacuum phototriodes. For the energy of incident photons from 100 to 700 MeV the energy resolution is 4-8% and angular resolution is 0.02-0.03 rad in agreement with MC simulation. (C) 2000 Elsevier Science B.V.
