摘　　要：介绍了一种应用于脉冲中子时间谱测量的新型亚纳秒有机闪烁纤维中子探测器,叙述了这种中子灵敏型探测器的探测原理,详细阐述了探测器的结构设计及具体的制作工艺,并给出了达到的技术指标。同时报道了为制作探测器而研制的一种新型亚纳秒有机闪烁纤维,介绍了闪烁纤维的选材、制作及其时间响应特性。A new sub-nanosecond neutron detector with plastic scintillation fiber is introduced, which is applied in the time spectrum measuring of neutron. Also, the principle, structural design and the specific production process of this type of sensitive neutron detector are described. Then, the indicators of detec- tor technical are given. In addition, a new sub-nanosecond plastic scintillation fiber has been studied, which is used for producing detectors. The material selection, the producing and the time response char- acteristics of the plastic scintillation fiber are introduced.
