Abstract

Lithium Indium Selenide (LiInSe₂) has been under development in RMD Inc. and Fisk University for room temperature thermal neutron detection due to a number of promising properties. The recent advances of the crystal growth, material processing, and detector fabrication technologies allowed us to fabricate large detectors with 100 mm² active area. The thermal neutron detection sensitivity and gamma rejection ratio (GRR) were comparable to ³He tube with 10 atm gas pressure at comparable dimensions. The synthesis, crystal growth, detector fabrication, and characterization are reported in this paper.
