论文摘要
我们介绍了在kilotesla级施加的磁场中激光驱动的鞘离子加速度的第一个3D粒子模拟。应用的磁场在与热电子鞘的随时间变化磁化有关的加速过程中产生了两个不同的阶段，并导致聚焦，磁场定向的多个物种的离子源具有强烈增强的能量和数量。在2D模拟中淡化了添加磁场的好处，这强烈表明在实验相关条件下观察磁场效应的可行性。
We present the first 3D particle-in-cell simulations of laser driven sheath-based ion acceleration in a kilotesla-level applied magnetic field. The applied magnetic field creates two distinct stages in the acceleration process associated with the time-evolving magnetization of the hot electron sheath and results in a focusing, magnetic field-directed ion source of multiple species with strongly enhanced energy and number. The benefits of adding the magnetic field are downplayed in 2D simulations, which strongly suggests the feasibility of observing magnetic field effects under experimentally relevant conditions.
