摘　　要：利用蒙特卡罗通用程序MCNP模拟了中国散裂中子源(CSNS)靶站中子的慢化和屏蔽.CSNS靶站通过1.6 GeV质子打到钨靶上,产生高能中子,经慢化器慢化后通过中子束道引入到各类中子谱仪中.本文的计算机模拟结果可为靶站中子的慢化和屏蔽的效果提供相关参考信息.It has been simulated by using MCNP for the moderating and shielding neutrons in the target station of CSNS. In the target of CSNS, high-energy neutrons are produced by the 1.6 Gev protons hitting the tungsten target. After being moderated, neutrons are led to the various spectrometer. The simulation results can provide information for the effect about the neutrons moderating and shielding in the target station of CSNS.
