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.
