摘要

The properties of ZnS(Ag)/(LiF)-Li-6 samples with three different mass ratios were studied. The study showed that the EJ426 sample with the mass ratio of 3:1 had the highest detection efficiency of thermal neutrons, which was 32.4% in the experiment. Furthermore, this sample had the largest charge spectrum. The light yield of its surface at the average value of the charge spectrum was approximately 8.01 x 10(3) photons/neutron. The gamma sensitivity of the sample was better than 10(-6) at the threshold of 350 photoelectrons. Therefore, EJ426 is a good candidate for a position-sensitive thermal neutron detector.
