“…Other articles on the response of scintillator materials to neutrons and gamma rays have been published, including Refs. [12][13][14][15][16][17][18][19][20][21][22][23][24]. Simulations of spectra resulting from photon interactions for a variety of sources with NaI(Tl) and PVT-based gamma-ray detectors have been reported by Siciliano et al [25].…”

“…Here, we ignored the light output from carbon recoils for two reasons: first, the average energy transferred to carbon per captured neutron is very small; second, the light yield of carbon is much less than that of a proton of the same energy [25]. The combination of these two effects leads to an overall negligible contribution of carbon recoils to the total light output for the neutron energy region studied [27]. The obtained proton light output in each interaction was then broadened by the detector energy resolution function.…”

An exothermic neutron capture reaction can be used to uniquely identify neutrons in particle detectors. With the use of a capture-gated coincidence technique, the sequence of scatter events that lead to neutron thermalization prior to the neutron capture can also be used to measure neutron energy. We report on the measurement of thermalization light yield via a time-of-flight technique in a polyvinyl toluene-based scintillator EJ-290 within a heterogeneous composite detector that also includes 6 Li-doped glass scintillator. The thermalization light output exhibits a strong correlation with neutron energy because of the preference for near-complete energy deposition prior to the 6 Li(n,t) 4 He neutron capture reaction. The nonproportionality of the light yield from nuclear recoils contributes to the observed broadening of the distribution of thermalization light output. The nonproportional dependence of the scintillation light output in the EJ-290 scintillator as a function of proton recoil energy has been characterized in the range of 0.3-14.1 MeV via the Birks parametrization through a combination of time-of-flight measurement and previously conducted measurements with monoenergetic neutron sources.

The design and analysis of measurements performed with organic scintillators rely on the use of Monte Carlo codes to simulate the interaction of neutrons and photons, originating from fission and other reactions, with the materials present in the system and the radiation detectors. MCNP-PoliMi is a modification of the MCNP-4c code that models the physics of secondary particle emission from fission and other processes realistically. This characteristic allows for the simulation of the higher moments of the distribution of the number of neutrons and photons in a multiplying system. The present report describes the recent additions to the MCNP-PoliMi post-processing code. These include the simulation of detector dead time, multiplicity, and third order statistics.
