Scintillation light simulation in big-sized BaF${}_2$ and pure CsI crystals

Abstract

We have investigated scintillation light distribution in BaF${}_2$ and pure CsI crystals with dimensions 3x3x20 cm${}^3$ using the Geant4 toolkit. The diffuse wrapping material is selected as coating for the crystals. The simulated cosmic muons and 105 MeV electrons are used as beam particles. The optical attenuation along the crystals is explored with the simulation data. We have demonstrated the impact of the crystal surface finish on the light distribution at the crystal end, optical photon arrival time, incidence angle distributions, and optical attenuation for the studied crystals.
