Abstract
© 2021 Elsevier B.V. A radiation detection system consisting of an array of three Cs2LiYCl6:Ce3+ elpasolite cells was studied for simultaneous, directional neutron and gamma-ray measurements. Utilizing a neutron source and gamma-ray sources, measurements were carried out while rotating the three-cell array 360°. The measurement data was processed using a maximum likelihood estimation technique to determine the most probable angle pointing to the radioactive source. The detection system enables measuring gamma rays and neutrons simultaneously and estimating locations of radioactive sources within 23°.
