摘要: 基于氚(氘)钛固体靶,利用TARGET程序结合实际的氚(氘)靶和靶室建模,对D-T中子和D-D中子的能量和微分截面角分布、氘离子能量损失率和平均能量、中子平均能量和能散、反应率在氚(氘)钛靶中的深度分布、中子注量率谱和中子产额进行了计算,获得了D-T和D-D中子的相关特性参数。计算结果可为在其他蒙特卡罗模型中精确描述各项异性中子源提供数据,对中子能量单色性和中子产额等指标的选择提供了参考数据。

Abstract: A Monte Carlo model was modeled based on the TARGET code and titanium tritide/titanium deuteride solid target. The angular distribution for D-T and D-D reaction neutrons, differential cross sections, energy loss and mean energy of deuteron ions, mean energy and energy straggling for neutrons, depth distribution for reaction frequency, neutron flux spectra and yields were calculated based on the parameter of the actual Ti T and Ti D targets. The characteristics of the D-T and D-D neutrons were obtained and discussed. The results can be used to describe an anisotropic neutron source accurately in other Monte Carlo models, and it can also provide a reference for the selection of monochromatic neutrons and neutron yields.
