Optimization of the structure of an electromagnetic calorimeter with longitudinal arrangement of absorbing and scintillating layers

摘要

A new layout of the absorbing and scintillating layers is proposed in order to suppress the channeling effect in an electromagnet'c calorimeter where these layers are parallel to the beam. The energy resolution of this calorimeter is estimated for different geometric parameters. A weaker angular dependence is observed at angles >30 mrad.
