摘要

As a candidate for the alternatives to 3He neutron detector, 2 inch size LiF-based eutectic composites were fabricated by Bridgman technique. The eutectic composites showed a good transparency and well ordered lamellar structure. Neutron response of the several eutectic composites were evaluated and LiF/SrF2:Ce performed the better alpha/gamma ratio and high light yield. The preliminary test of neutron imaging detector consists of LiF/SrF2:Ce and PSPMT was carried out and the detector performed a good spatial resolution.
