“…The difference between the results of simulation 2018 JINST 13 P03005 and measurement may be due to the reasons like utilized material cross section in the MCNPX computational code, modeling of the generation of light output, modeling of the transport of light and the available errors of considered scintillation light resolution function. Neutron light output distributions reported by other published works show a similar behavior [18]. The simulated gamma light output distribution of 241 Am- 9 Be source has some difference to the result obtained from experiment.…”

In the present paper, the light output distribution due to poly-energetic neutron/gamma (neutron or gamma) source was calculated using the developed MCNPX-ESUT-PE (MCNPX-Energy engineering of Sharif University of Technology-Poly Energetic version) computational code. The simulation of light output distribution includes the modeling of the particle transport, the calculation of scintillation photons induced by charged particles, simulation of the scintillation photon transport and considering the light resolution obtained from the experiment. The developed computational code is able to simulate the light output distribution due to any neutron/gamma source. In the experimental step of the present study, the neutron-gamma discrimination based on the light output distribution was performed using the zero crossing method. As a case study, 241 Am-9 Be source was considered and the simulated and measured neutron/gamma light output distributions were compared. There is an acceptable agreement between the discriminated neutron/gamma light output distributions obtained from the simulation and experiment.
