对伴随α粒子法测量DT中子源中子注量系统的稳定性及重复性进行了检验。通过铁活化法与伴随粒子法得到的中子注量相比较,完成了预备实验。用4πβ(PC)-γ符合标准装置测量活化后的铝箔的方法与伴随粒子法监测的中子注量率比对,两者偏差小于伴随粒子法的扩展不确定度,其中伴随粒子法标准不确定度为1.6%,铝活化法标准不确定度为1.8%。 The stability and repeatability of DT neutron source neutron flux measurements with the alpha particle method were examined. Compared with the neutron fluence obtained by the iron activation method and the accompanying particle method, preliminary experiments were completed. The method of measuring the activated aluminum foil with a 4πβ (PC) -γ standard device is compared with the neutron fluence rate monitored by the particle method, and the deviation between them is smaller than that of the extended particle size method. The degree of certainty is 1.6% and the standard uncertainty of aluminum activation method is 1.8%.
