    Abstract:

    The pure Cherenkov radiator Lead Fluoride (PbF2) is for the first time used as a material for a medium scale (1022 crystals) fast (20ns dead time) homogeneous absorbing electromagnetic calorimeter with good energy resolution . It allows event recording rate of close to 100 MHz in the solid angle of the calorimeter corresponding to single channel event processing rates of 100-200 kHz depending on scattering angle. The first experiences after 1500 hours of successfull beam time are summarized and the performance concerning calibration and energy resolution for the first 511 channels is presented here.
