摘要
介绍了一种在144keV^2.5MeV具有较平坦的能量响应的银活化探测系统,它采用特殊慢化体结构。将该探测器初步应用到了12MeV LIA的中子测量中,给出了中子产额的初步结果,中子产额分布在2.6×109~3.7×109个/脉冲。
A silver activation detector, whose modular design allows several efficiency vs. energy responses is the almost same from 144keV to 2.5MeV has been described. This detection system then is used in the LIA of 12MeV to measure the neutron flux of （X,n） reaction and obtained that neutron yield is 2.6×10^9～3.7×10^9 n/pulse.
