^(63)Cu活化法测量10~7DT脉冲中子产额

Absolutely Measuring DT Impulse Neutron Yieldsof 10~7 Range with ^(63)Cu Active Method

介绍了用63Cu活化法绝对测量产额在107左右的脉冲中子的实验方法,给出了脉冲产额的计算公式,对其测试系统的DT中子灵敏度进行了标定,给出了脉冲中子产额绝对测量数据,分析了其测量不确定度来源,获得了不确定度为12%(k=1)的实验结果。

The method of 63Cu activity of measure DT impulse neutron yields of 10^7 range is introduced, which involves its calculation formula, and system sensitivity calibration in the accelerator, and data of neutron yields emitted by the small DT generator. As a result, 12% of its uncertainty is given.
