摘要
介绍了一种用于中子—伽玛混合场中探测裂变中子参数的新型光纤探测组件,该组件仅对从轴向入射的中子灵敏,而且时间响应快(ns级),配备不同的光电探测元件后辐射灵敏度和线性电流可调。重点介绍了裂变中子探测组件的探测原理、关键技术和解决途径,并给出产品达到的技术指标。
The new optical fiber neutron detecting assembly is introduced in this article, which is used for detecting fission neutron parameters in the neutron-γ mixing field. The assembly is only sensitive to neutrons launched from the axial direction and possesses the fast time respond （ns grade ）. The radiation sensitivity and the linear current can be adjusted by using different photoelectric detecting components. The detecting principles of the fission neutron detecting assembly are introduced emphatically. The key technologies and their solving ways are presented, and the specifications of the product are presented.
