The material lithium indium diselenide, a single crystal neutron sensitive semiconductor, has demonstrated its capabilities as a high resolution imaging device. The sensor was prepared with a 55
m pitch array of gold contacts, designed to couple with the Timepix imaging ASIC. The resulting device was tested at the High Flux Isotope Reactor, demonstrating a response to cold neutrons when enriched in 95%
Li. The imaging system performed a series of experiments resulting in a <200
m resolution limit with the Paul Scherrer Institute (PSI) Siemens star mask and a feature resolution of 34
m with a knife-edge test. Furthermore, the system was able to resolve the University of Tennessee logo inscribed into a 3D printed 1 cm
plastic block. This technology marks the application of high resolution neutron imaging using a direct readout semiconductor.
