Transuranic elements like Plutonium are radioactive materials which spontaneously emit neutrons. A neutron detector is therefore a crucial tool to detect illicit trafficking of radioactive materials that could be used to make nuclear or dirty bombs. It is also an important tool for radio-protection at nuclear facilities. Currently most neutron detectors in use are based on Helium-3 gas tubes. The current shortage of Helium-3 means that the supply can no longer meet the demand. Alternative technologies are needed in order to replace Helium-3 systems already deployed. This project aims to replace successfully Helium-3 detectors used as hand held and backpack system by a new technology based on layers of neutron sensitive material mixed with highly efficient scintillator. The technology is easily scalable and the design flexible enough to meet a wide range of detector requirements.

像钚这样的超铀元素是自发发射中子的放射性物质。因此，中子探测器是侦查可用于制造核弹或脏弹的放射性材料非法贩运的重要工具。它也是核设施无线电防护的重要工具。目前使用的大多数中子探测器都是基于氦-3气体管的。目前氦-3的短缺意味着供应已不能满足需求。需要替代技术，以取代已经部署的氦-3系统。该项目旨在用一种基于多层中子敏感材料和高效闪烁体的新技术成功地取代用作手持式和背包系统的氦-3探测器。该技术易于扩展，设计足够灵活，可以满足广泛的探测器要求。
