Abstract
The endcap calorimeter of the CMD-2 detector for the VEPP-2M collider is described. The calorimeter contains 680 EGO crystals read out by va cuum phototriodes. Charge sensitive preamplifiers are placed directly on the phototriodes for the best noise performance. The calorimeter wa s installed during the last year. Calibration by cosmic rays showed th e energy equivalent of the electronic noise to be about 0.9 MeV during operation in a 1 T magnetic field which corresponds to the design val ue.
