介绍了一种利用同位素中子源 (2 41Am 9Be)通过γ n符合的中子飞行时间法对大面积探测器的中子探测效率进行刻度的方法 ,并用蒙特卡罗方法对该探测器的探测效率进行了模拟 .实验与模拟结果基本一致 . A method of calibrating neutron detection efficiency of a large area detector by means of neutron time-of-flight γ n isotope neutron source (2 41Am 9Be) is introduced. The Monte Carlo method is used to detect the detector Efficiency is simulated.The experimental and simulation results are basically the same.
