Abstract
A neutron sensing material detector includes an anode; a cathode; and a semiconductor material disposed between the anode and the cathode. An electric field is applied between the anode and cathode. The semiconductor material is composed of a ternary composition of stoichiometry LiMGand exhibits an antifluorite-type ordering, where the stoichiometric fractions are Li=1, M=1, and G=1. Electron-hole pairs are created by absorption of radiation, and the electron-hole pairs are detected by the current they generate between the anode and the cathode. The anode may include an array of pixels to provide improved spatial and energy resolution over the face of the anode. The signal value for each pixel can be mapped to a color or grey scale normalized to all the other pixel signal values for a particular moment in time. A guard ring or guard grid may be provided to reduce leakage current.
