摘　　要：为降低中子防护体厚度,用高密度金属与金属吸氢材料组成的双层材料防护产额为108个/s的D-T中子发生器.MCNP模拟结果显示,在中子辐射剂量小于0.025 mSv/h的情况下,双层材料的最小厚度为45 cm,采用的材料是W和TiH2,厚度分别为36和9 cm.In order to reduce the thickness of neutron shield,the double-layer material composed of high-density metal and metal hydrogen absorbing material is used to protect the D-T neutron generator with a yield of 108 n/s.MCNP simulation results show that when the neutron radiation dose is less than 0.025 mSv/h,the minimum thickness of the double-layer material is 45 cm,the materials used are W and TiH 2,and the thicknesses are 36 cm and 9 cm respectively.
