摘要
采用反应堆不同的运行功率和缓发中子不同时刻的衰减作为模拟源,测量出两套计数率测量仪的死时间分别为3.65和5.18μs,并提出利用反应堆的功率周期上升测量计数率测量仪死时间的方法。
The dead time of two counter rate measuring instruments was determined by reactor operated at several power level and by delayed neutron decay curve.The mean dead time of two counter rate measuring instruments by uncertainty weight is 3.65 μs and 5.18 μs,respectively.And another method to measure dead time of counter by reactor power increase was presented.
