Modelling and data processing in electromagnetic calorimeters with cellular structure

The shower hodoscopic detectoi is an important part of various up-to-date detectors in experimental physics. It is a calorimeter with rectangular cells. In the present paper we consider a model of the distribution of energy release in the calorimeter cells and propose an analytical solution of the problem of fitting the model distribution experimental data. The corresponding programme was included into the calorimeter software and allowed one to raise the rate of data processing (compared to the classical methods of fitting) 8–9 times with about 10% reliability increase.
