摘要 基于二维激光靶耦合流体力学程序,研究设计惯性约束聚变间接驱动点火黑腔的方法.提出先调控X射线驱动温度再调控辐照均匀性的设计顺序.给出总激光功率(特别是主脉冲激光功率)的设计方法.模拟表明,填充气体密度的上限受到槽脉冲P2辐照不均匀性的限制.另外,增加腔长可以抑制靶丸烧蚀层物质的膨胀.最后给出点火黑腔二维设计结果. We introduce an ignition hohlraum 2D-simulation design method with 2D code.A design sequence,in which X-rays drive tempetature is tuned before P2 asymmetry,is put forward.Details in designing laser power is studied.It indicates that control of P2 asymmetry during trough pulse limits the maximum of filling gas density and expansion of capsule ablator can be restrained by longer drive pulse.An ignition hohlraum 2D-simulation design is given.
