摘要
高产率惯性聚变为经济实惠的清洁稳定电力和先进防御能力提供了一条变革性路径。大型设施（特别是国家点火装置 NIF）近期的里程碑证明了点火的可行性，但也凸显了对能够以更高效率和更低成本向聚变靶输送大量能量的方法的需求。我们提出由脉冲发生器驱动的惯性聚变能 (IFE)，该方案利用高电流脉冲功率技术将靶压缩至热核条件，能够实现这一目标。在本文中，我们详细介绍了脉冲发生器 IFE 的物理基础，重点探讨了磁化套筒惯性聚变，其中圆柱形金属套筒在强磁场和预热条件下压缩 DT 燃料。我们讨论了低内爆速度、直接驱动效率和可扩展的脉冲发生器架构如何能够以低资本成本实现点火级条件。我们以 Z 装置上的实验为基准的多维模拟表明，将电流从 20 MA 缩放至 50-60 MA 即可实现设施净增益。随后我们介绍了我们的演示系统 (DS)，这是一种旨在提供超过 60 MA 电流并储存约 80 MJ 能量的脉冲功率驱动器。DS 的设计旨在实现比 NIF 高出 1000 倍的有效性能，提供约 100 倍的设施级能量增益——且重要的是，仅以 1/10 的资本成本实现设施净增益，即 Qf>1。我们还探讨了重复运行、靶制备和腔室维护的工程要求，突出了通往商业核电站的实用路线图。
