Abstract

We describe research on developing more effective means to shield gamma-ray detectors from neutron-induced background. Conventional active shields are very inefficient in vetoing neutrons. Neutron-induced background is exacerbated in new classes of gamma-ray detectors such as CZT, which have large neutron interaction cross-sections. An approach to this problem is supershields, which contain separate layers to moderate and absorb neutrons. We show how supershields are superior to monolayer neutron shields which have been studied previously.
