摘要
对便携式D-D中子发生装置进行产额测试、验证及均匀性、稳定性测量,并将其用于对批量中子探测器的中子响应检测。实验结果表明:D-D中子发生装置的中子产额能够满足相关国标的要求;与252Cf中子源测试结果进行产额验证,偏差为-7.4%;D-D中子发生装置中子场的不均匀性为10%,中子产额的稳定性为7.0%;批量_(3)He中子探测器的检测结果表明采用D-D中子发生装置进行检测是可行的,可为中子发生装置代替同位素中子源对_(3)He中子探测器检测提供技术参考。
The portable D-D neutron generator is used for yield test,verification and uniformity and stability measurement,and it is used for the neutron response detection of batch neutron detectors.The experimental results show that the neutron yield of the D-D neutron generator can meet the requirements of relevant national standards;the yield is verified with the test results of the 252Cf neutron source,and the deviation is-7.4%;The uniformity of the neutron field of the D-D neutron generator is 10%,and the stability of the neutron yield is 7.0%;The detection results of batch _(3)He neutron detectors show that it is feasible to use D-D neutron generators for detection,which can provide technical reference for the detection of _(3)He neutron detectors in neutron generators instead of isotopic neutron sources.
