本文给出了离子束惯性聚变靶中辐射可以补偿射程缩短的计算机模拟结果。还报告了重离子束驱动的反应堆尺寸惯性约束聚变（ICF）靶（包括辐射输运）的烧蚀、压缩、点火、燃烧和流体动力学稳定性的模拟结果。在这种靶设计中，通过高Z、高ρ的铅辐射屏蔽来保护燃料免受辐射预热，并且通过低Z、低ρ的锂垫将燃料与辐射屏蔽分开。这避免了在内爆结束时来自辐射屏蔽的铅混入燃料中。该靶由10 GeV Bi++离子驱动，并且对于104.56 MJ的输入能量，其产生10690 MJ的输出能量，使得总靶增益为10152。输入脉冲的峰值功率为500 TW。
In this paper computer simulation results showing that radiation can compensate for range shortening in ion‐beam inertial fusion targets are presented. Simulation results of ablation, compression, ignition, burn, and hydrodynamic stability of a heavy ion‐beam‐driven, reactor‐size, inertial confinement fusion (ICF) target including radiation transport are also reported. In this target design the fuel is protected against radiative preheat by a high‐Z, high‐ρ lead radiation shield, and the fuel is separated from the radiation shield by a low‐Z, low‐ρ lithium cushion. This avoids mixing of the lead from the radiation shield into the fuel at the end of the implosion. The target is driven by 10 GeV Bi++ ions, and it yields an output energy of ∼690 MJ for an imput energy of ∼4.56 MJ, so that the overall target gain is ∼152. The peak power in the input pulse is 500 TW.
