SIMULATION OF GEOMETRICAL AND OTHER FACTORS IN SCINTILLATION-COUNTERS

Monte Carlo simulation is used to evaluate the behavior of light produ ced by charged particles in scintillation counters. We take into accou nt the scintillation counters' geometrical shape as well as its surfac e optical absorption and its surface finishing. Local light production is estimated using the model of Michaelian and Menchaca-Rocha [1]. Ab sorption mechanisms are shown to introduce range-dependent effects whi ch are most important when the penetration of the particles is compara ble to the depth of the scintillator.
