Development of a scintillation and light transport simulator — •José Ricardo Avelar-Rivas and Jürgen Henniger — ASP, IKTP, TU Dresden, Zellescher Weg 19, 01069 Dresden, Germany

Accurate modeling and simulation of radiation detectors, among other benefits, lead to improvements in efficiency, increase reliability and sensitivity of the measuring technique, allows easy testing and decrease costs related to the experimental design and set up. In scintillation detectors is known that the link between the scintillator material, the light detector and the analyzer electronics is crucial for the development, improvement and optimization of scintillator-based detection systems. To simulate radiation detectors there are available several well-known Monte Carlo general purpose codes. Most of them were initially developed for individual or coupled particle-photon transport and do not allow the simulation of light generation and transport of optical photons through scintillation materials, perform an incomplete light transport simulation or the light transport simulation is inexistent. Therefore, a precise and fast scintillation and light transport simulator is being developed.

In its first stage, this work focuses on the simulation of light generation in scintillation materials and light photon transport through the material. In contrast with other existing Monte Carlo codes, this code will follow each light photon through all interactions within the scintillation material until it goes out of the crystal, it is absorbed or it reaches a selected surface. The results of the implementation will be shown in this presentation.
