已经开展了一项广泛的研究方案，研究能够辨别中子-伽马射线的闪烁液和塑料，以便在未来的被动和主动国土安全系统中部署，提供针对放射性和核威胁的保护。将更成熟的检测材料如EJ-301和EJ-309与新材料如EJ-299-33和对三联苯进行比较。本研究还探讨了从模数采样率和采样位分辨率的改进中可以获得的好处。结果上的脉冲形状歧视性能的各种探测器和数据采集组合，以及如何从这些研究的最佳配置已发展成为现场准备就绪的探测器阵列。从应用特定的实验配置的多元探测器阵列的早期结果。
An extensive programme of research has been conducted for scintillation liquids and plastics capable of neutron–gamma discrimination for deployment in future passive and active Homeland Security systems to provide protection against radiological and nuclear threats. The more established detection materials such as EJ-301 and EJ-309 are compared with novel materials such as EJ-299-33 and p-terphenyl. This research also explores the benefits that can be gained from improvements in the analogue–to–digital sampling rate and sample bit resolution. Results are presented on the Pulse Shape Discrimination performance of various detector and data acquisition combinations and how optimum configurations from these studies have been developed into field-ready detector arrays. Early results from application-specific experimental configurations of multi-element detector arrays are presented.
