摘要
介绍了一新型的用于(n,2n)反应截面测量的由"80根3He正比计数管和聚乙烯慢化体"组成的3He球形4π中子探测器的优化设计,并采用蒙特卡罗方法计算了探测器系统的单位中子能量注量响应,提高了探测器的设计效率,也为实验验证提供参考依据。
It introduced the design of a newly 4π neutron detector used to measure（n,2n） cross section and composed by 80 3He proportional counters and a large spherical polyethylene moderator,and the Monte Carlo method was used to calculate the unit neutron energy fluence response of the detector system,which not only improved the design efficiency,but also provided a reference for the following experiment.
