【摘要】 本文利用GEANT4程序包对Micromegas作为中子探测器时的位置分辨率进行了蒙特卡罗模拟。同时,利用时间符合技术采用了一种新的径迹重建方法——延迟法。通过模拟得到了位置分辨率随中子通量的变化情况,证明了采用这种新的径迹重建方法能够得到较好的位置分辨率。利用这种径迹重建方法可以将Micromegas中子探测器应用到高中子通量的核裂变和核反应堆实验中。更多还原

【Abstract】 In this paper,the simulation of the spatial resolution of Micromegas as neutron detector was done by GEANT4 toolkit.The neutron track reconstruction method(delay method)based on the time coincidence technology was employed in the present work.By simulation,the variation of the spatial resolution of Micromegas with different primary neutron flux was studied.Our results show that the delay method can provide better spatial resolution.The new concept of neutron detection can be used in some fusion experiments or experiments with nuclear reactor, which are characterized by very high neutron flux.更多还原
