Abstract

Semiconducting lithium indium diselenide, ⁶LiInSe₂ or LISe, has promising characteristics for neutron detection applications. The 95% isotopic enrichment of ⁶Li results in a highly efficient thermal neutron-sensitive material. In this study, we report on a proof-of-principle investigation of a semiconducting LISe pixel detector to demonstrate its potential as an efficient neutron imager. The LISe pixel detector had a 4×4 of pixels with a 550 µm pitch on a 5×5×0.56 mm³ LISe substrate. An experimentally verified spatial resolution of 300 µm was observed utilizing a super-sampling technique.
