主动旋转法是一种创新的、可运输的、主动中子法,适用于现场探测隐藏的核材料。它的分析系统主要由一个中子探测器和一个旋转装置组成,旋转装置用于旋转中子源,如california-252。虽然我们之前展示了一种低成本的旋转装置,但包括氦-3正比计数器的中子探测器组非常昂贵,并且探测效率低,这就带来了降低成本和测量时间的挑战。在本研究中,我们开发了一种水切伦科夫中子探测器作为一种新型的中子探测器的主动旋转方法,并证明了其适用性和有效性的核材料检测,满足成本,效率和可运输性标准的核安全。
The active rotation method is an innovative, transportable, active neutron method suitable for on-site detection of concealed nuclear material. Its assay system consists mainly of a neutron detector and a rotation device for rotating a neutron source such as californium-252. Although we previously demonstrated a low-cost rotation device, the neutron detector bank comprising helium-3 proportional counters was extremely expensive and had low detection efficiency, leaving the challenges of reducing cost and measurement time. In the present study, we developed a water Cherenkov neutron detector as a novel neutron detector for the active rotation method and demonstrated its suitability and effectiveness for nuclear material detection, meeting the cost, efficiency, and transportability criteria for nuclear security.
