为了测量ICF内爆实验聚变反应的时间过程，建立了计算机MonteCarlo光线追迹程序进行光学辅助设计，研制了主要由BC422塑料闪烁体、消色差透镜组、皮秒条纹像机和制冷增强CCD组成的超快脉冲中子探测系统，其时间响应＜40ps。闪烁体与靶丸的最短距离可达2cm，测量下限中子产额为～108。
In order to measure the time course of ICF implosion experimental fusion reaction, a computer MonteCarlo ray tracing program was set up for optical assistant design. The main work consisted of BC422 plastic scintillator, achromatic lens, picosecond stripe camera and refrigeration enhanced CCD Ultrafast pulsed neutron detection system with a time response of <40ps. The shortest distance between the scintillator and the target is up to 2 cm, and the lower limit neutron yield is ~ 108.
