Abstract :
The endcap calorimeter of the CMD-2 detector for the VEPP-2M collider is described. The calorimeter contains 680 BGO crystals read out by vacuum phototriodes. Charge sensitive preamplifiers are placed directly on the phototriodes for the best noise performance. The calorimeter was installed during the last year. Calibration by cosmic rays showed the 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 value
