| 摘 要： | 采用视角因子方法,对间接驱动惯性约束聚变(ICF)过程中从腔内壁辐射到靶丸表面的辐射进行了计算,并分析了激光原型装置上的一个实验的对称性环境。间接驱动ICF系统的不对称性一般来自于激光焦斑和腔体的几何结构,利用视角因子方法,计算X光能量在腔体内的强度分布,将靶丸表面的驱动对称性表示成腔体结构和激光焦斑几何参数的函数。结果表明,采用该方法的程序模拟能够评估腔靶设计的主要参数。

| Abstract: | A view-factor method for calculating the radiation drive from hohlraum walls to the capsule in indirect inertial confinement fusion (ICF) has been presented, with which asymmetry conditions for implosion experiments on laser prototype were evaluated. X-ray intensity distribution on the hohlraum walls was calculated as well as the radiation drive on the capsule located in the center of the cylindrical gold target. The drive nonuniformity varying with the laser-spot locus and the hohlraum geometry were also given. The results show that this method helps to assess the main parameters of indirect ICF targets and provides useful information for experiment design. |
