摘要：

A thin CdTe thermal neutron detector has been developed and its suitability for neutron imaging has been investigated. Simulations of the interaction of neutrons with a 0.5 mm-thick CdTe detector demonstrate the advantages of using 96 key prompt gamma rays produced by neutron capture in Cd-113 as a neutron event. Specifically, they provide a high spatial resolution and approximately the same detection efficiency as 558 keV prompt gamma rays, which are commonly used for detecting thermal neutrons in CdTe detectors. We fabricated a thin CdTe detector. Measurements using a Ba-133 gamma-ray source revealed that the detector has a gamma-ray energy resolution of 3 key at 80 key, while measurements using a Cf-252 neutron source demonstrated that the CdTe detector has good neutron/gamma ray discrimination.
