| 摘 要： | 根据现有的中子探测器多采用气体探测材料,普遍存在体积大,效率不高和响应时间长的缺点,结合中子探测的最新发展,用蒙特卡罗方法通用软件MCNP(4B版本)对中子探测材料和结构进行了研究,并在此基础上设计出了一种新型中子探测器模型,对它的探测性能进行了数值仿真。该新型中子探测器的设计不论是对民用还是对军用都将有着十分重要的意义。 |

| Abstract: | Based on that the neutron detectors used now have some disadvantages such as low detection efficiency, long response time, etc, studied the new development of neutron detection a new type of neutron detector prototype using plastic scintillator BC454 and inorganic scintillator BGO as the detection medium was proposed. Simulation of its detection efficiency and other parameters was done using Monte Carlo general code MCNP (Version 4B). This new kind of portable neutron detector with high detection efficiency and sensitivity is strongly needed. |
