摘　　要：介绍了测定聚变中子产额铜活化法的原理、γ-γ符合计数系统、软件结构和功能、标定等。γ-γ符合计数系统中 ,辐照样品的计数指令发出后 ,计数、存储、数据处理到输出最终测量报告 ,全部由计算机进行控制 。The direct implosion experiments, in which the glass microballoons are filled with DT fuel, are very successful at Shenguang II laser facility in 2000. One of the ways to measure the fusion neutron yield is the 63Cu activation. The principle of the Cu activation, γ-γ coincidence counting system, its software structure and function, and calibration are presented. After the counting order of the radiated sample counting, saving, data analyzing and treatment, printing of the result and so on are all controlled by the computer, so that the reliability and working efficiency are improved.
