Abstract

Abstract: A radiation detection system consisting of an array of Cs2 LiYCl6 :Ce 3+ elpasolite cells was studied for simultaneous neutron measurements and gamma-ray spectroscopy. The system allowed directional detection with the localization of radiation sources. Computational modeling of detector array showed that the three-cell detector array is feasible to determine the direction to a neutron source and a gamma-ray source. Highlights: Elpasolite detection system was studied for directional measurements of neutrons and photons. Computational study of elpasolite scintillator responses was carried out using MCNP6 code. Maximum likelihood estimation technique was used to localize a radiation source. Three-cell array is feasible to determine the direction to a neutron source and a gamma-ray source.
