SIMULATION STUDIES OF THE ELECTROMAGNETIC ENERGY RESOLUTION OF SCINTILLATING-FIBER CALORIMETER

Using a Monte Carlo code based on the GEANT package the energy resolut ion of a scintillating fibre calorimeter was investigated as a functio n of the volume ratio of passive (absorber) to active (fibres) materia l, fibre radius, light reflection coefficient at fibre end, fibre tran sparency, and incident particle tilt angle. The obtained MC results we re confronted with the existing experimental data. Good agreement betw een the simulation and experiment was found in most cases. A simple fo rmula describing the stochastic term of the energy resolution as a fun ction of the calorimeter basic parameters has been found.
