Monte Carlo Simulation of NE213 Response to 241Am-Be Neutrons Using the PTRAC Card of the MCNPX Code and the Light Transport Code PHOTRACK

Abstract

The response of an NE213 scintillator to Am-Be neutrons, in which the neutron and neutron-induced charged particles transports have been undertaken, has been simulated with the use of MCNPX’ PTRAC card whilst the scintillation light transport has been performed with Monte Carlo light transport code, PHOTRACK. The scintillation light output for different neutron-induced charged particles has been calculated using the validated light output curves. The experimental data on the response of the NE213 scintillator exposed to Am-Be source has been obtained with a neutron-gamma discrimination circuitry using zero-crossing method. The simulation data represent a good agreement with the corresponding experimental results.
