Modelling plastic scintillator response to gamma rays using light transport incorporated FLUKA code

The response function of NE102 plastic scintillator to gamma rays has been simulated using a joint FLUKA+PHOTRACK Monte Carlo code. The multi-purpose particle transport code, FLUKA, has been responsible for gamma transport whilst the light transport code, PHOTRACK, has simulated the transport of scintillation photons through scintillator and lightguide. The simulation results of plastic scintillator with/without light guides of different surface coverings have been successfully verified with experiments.

► A multi-purpose code (FLUKA) and a light transport code (PHOTRACK) have been linked.
► The hybrid code has been used to generate the response function of an NE102 scintillator.
► The simulated response functions exhibit a good agreement with experimental data.
