摘 要: | 介绍了金刚石中子探测器主要性能的测试方法。采用14 MeV氘氚中子测试了金刚石中子探测器的稳定性和探测效率,实验结果表明探测器性能稳定,中子探测效率ε_E=8.00×10~(-5)(±9.38%)counts/n·cm~2。SuperMC蒙卡软件对探测效率进行模拟计算,计算结果ε_C=8.69×10~(-5)(±3%)counts/n·cm~2,不确定度范围内认为二者一致。

Abstract: | This paper introduces the testing methods of the main properties of the diamond neutron detector.The stability and the detection efficiency of diamond neutron detector were tested by 14 MeV D-T neutron.The experimental results show that the detector has stable performance, and neutron detection efficiency is εE=8.00×10-5(±9.38%) counts/n·cm2.Also the detection efficiency is simulated by SuperMC Monte Carlo software, the calculation results is εC=8.69×10-5(±3%) counts/n·cm2.It is considered that the two results are consistent within the uncertainty. |
