The cylindrical assembly of thorium oxide was irradiated by D-T neutrons.The Diameter of the assembly is 30 cm while the thickness is 15 cm.The neutron spectra of 1 MeV to 15 MeV were measured with stilbene using recoil proton method in several arrangements and the gamma spectra with energy above 0.5 MeV were also measured using recoil electronic method.The comparison and analysis were finished referring to the structure of spectra and its relationship with arrangement.%利用D-T中子对氧化钍圆柱装置进行了辐照.样品直径为30 cm、厚度为15 cm.在不同的布局状态下,采用芪晶体闪烁体基于反冲质子法对1 MeV~15 MeV中子能谱进行了实验测量;基于反冲电子法对中子辐照下和辐照后的0.5 MeV以上伽马能谱进行了测量.对能谱中的分布规律、与布局状态的关系进行了比对分析.
