摘要

根据D-T中子源260 keV氘束流能量下的中子能谱和角分布数据

建立了D-T中子源模型

在中子发生器各元件材料及实验大厅墙壁对快中子的慢化、散射和吸收的条件下

采用MCNP模拟程序对强流中子发生器n-γ辐射场进行了模拟研究

得到了中子能谱、中子和γ角分布、n-γ比等重要参数。模拟结果与有关文献实验数据的基本吻合

验证了所建立的MCNP模拟模型的可靠合理。

Abstract

A D-T neutron source model was constructed.The n-γ field distribution of the intense neutron generator with 260 keV deuteron beam at Lanzhou University was simulated using MCNP code.The interactions between neutron and the materials of neutron generator and the shielding walls were included in this study.The neutron energy spectrum

the angular distribution of neutron and γ-ray

and the n-γ ratio were presented.The M-C simulation results were compared to the experimental data to verify the reliability of the D-T neutron source model.
