Abstract
In this paper, on the basis of the Monte-Carlo simulation results a signal processing algorithm for determination of the energy deposited in real time by incident particles has been developed and implemented in the created electronics prototype of the trigger system for an electromagnetic calorimeter of the COMET experiment. The energy thresholds for trigger cells are determined which make it possible to select signal events – an electron with a momentum of 105 MeV/c, and significantly reduce a rate of background events. The electronics prototype of the trigger system has been verified by testbench measurements and electron beam experiments. The obtained results satisfy the key requirement of the calorimeter – the energy resolution in real time is better than 5 % for the signal electron energy.
