Positioning Error Budget in ICF Driver

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 element. Based on the relationship between the motion of the optical components and beam position on target, The position error budget 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 provided.
