Monte Carlo modeling of neutron sensitivity for foil- or fiber- plastic scintillator

Abstract

Based on the key reaction with neutrons within plastic scintillator and its fluorescence characteristic, Monte Carlo simulation method is introduced for neutron sensitivity calculation for foil- or fiber- plastic scintillator. The energy dependent sensitivities in the fission neutron energy range are calculated and discussed for various foil thickness and fiber diameters, which suggest a possible flat-response current-mode detector scheme for fission neutron measurement through combination of plastic scintillator foils with different thickness.
