大面积闪烁体探测器的中子探测效率刻度
Efficiency Calibration of Neutron Detectors with Large Area
【摘要】 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 .
【Abstract】 A method was developed for efficiency calibration of large area neutron detectors based on γ-n coincidence and time-of-flight techniques using a 241Am- 9Be neutron source. The detector efficiency was also calculated by a Monte Carlo code and compared to the experimental results.
