摘要：
A recently developed scintillator has been investigated for possible use as a dual detector for neutron and gamma spectrometry. A 7Li-enriched version of the scintillator has been investigated. The Cl-35(n,p)S-35 nuclear reaction provides a possibility for fast neutron detection. The sensor has been mounted on a photomultiplier tube controlled with a miniature electronics board and irradiated in different gamma and neutron radiation fields. A series of experiments has been carried out with different gamma energies as well as well with mono-energetic neutrons from a KN Van de Graaff accelerator, and the pulse height spectra have been measured. To clarify different features observed on the response functions of the detector, a Monte Carlo model of the scintillator has been built using MCNP6 and emitted charged particles have been tracked. The simulation data along with the experiments are analyzed, compared and reported. (C) 2015 Elsevier Ltd. All rights reserved.
