利用加权和法,将ICF物理实验对靶点的定位需求分配到各个组件对靶点的需求.运用等概率和不等概率方法,将组件对靶点的需求分配到各元件对靶点的需求.通过光学元件运动量与靶点光束定位之间的关系,确定各个元件定位误差估计值,并将其值作为光学元件定位误差变化范围,在此范围内进行上千条光线追迹法,根据正态分布区间估计法进行检验与修正,最后给出一组具有可行性的光学元件定位误差估计参考表.

This paper presents the method of linear weight sum to beam positioning budget on the basis of ICF request on targeting, the approach of equal or unequal probability to allocate errors to each optical elecent. Based on the relationship between the motion of the optical components and beam position on target, the position error of the optical components was evaluated, which was referred to as the maximum range. Lots of raytrace were performed, the position error budget were modified by law of the normal distribution. An overview of position error budget of the components is provided.
