论文摘要
在亚相关性等离子体Wakefield加速器中提出了一种新的电子注射方案。横向激光使掺杂气体电离并蓬松曲线量会沿唤醒传播方向加速释放的电子。这个过程即使是在捕获阈值以下的韦克菲尔德电位，也可以在韦克菲尔德中捕获电子捕获。我们从理论上并通过粒子中的粒子模拟研究了该方案，以证明具有高质量的束形成和加速度，并以亚微米计归一化的发射率和次级不相关的能量扩散。
A new electron injection scheme is proposed in sub-relativistic plasma wakefield accelerators. A transverse laser ionizes a dopant gas and ponderomotively accelerates the released electrons in the direction of wake propagation. This process enables electron trapping in the wakefield even for a wakefield potential below the trapping threshold. We study the scheme theoretically and by means of particle-in-cell simulations to demonstrate high-quality beam formation and acceleration with sub-micrometer normalized emittances and sub-percent uncorrelated energy spreads.
