研究了惯性聚变中锥空心辅助快速点火的新方案。传统金锥体的尖端附有一个空心部分。通过二维混合模拟研究了强电流电子从锥尖沿中空传播到压缩燃料核心的传输和加热。研究了不同的空心几何尺寸。结果表明,通过适当的空心引导,热电子可以通过内表面上出现的大界面磁场在空心内壁之间准直。当束流电子进一步传播到致密区域时,它们通过与燃料电子和离子的碰撞而散射到金空心中。然后,空心周围产生的磁势使电子束沿着金空心弯曲,到达致密的核心。
A new scheme for cone-hollow-assisted fast ignition in inertial fusion is investigated. A hollow is attached to the tip of a conventional gold cone. The transport and heating of the high-current electrons propagating from the cone tip to the compressed fuel core along the hollow is investigated by two-dimensional hybrid simulation. Different hollow geometry sizes are examinized. It is shown that with proper hollow guiding, hot electrons can be collimated between the inner-walls of the hollow by the large interface magnetic fields appearing on the inner surface. When the beam electrons further propagate into the dense region, they are scattered into the gold hollow through collisions with the fuel electrons and ions. The resulting magnetic potential around the hollow then bends beam electrons along the gold hollow to reach the dense core.
