Directional detection of neutrons and photons using elpasolites: Computational study

Abstract A radiation detection system consisting of an array of Cs 2 LiYCl 6 :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.
