摘要

本文研究了利用等离子体中新的电子密度跃迁,降低了破波阈值,增加了尾流场加速阶段的横向电子注入。数值结果表明,注入的电子束引起了尾流场的改变。通过优化电子的瞬态长度和注入电荷,计算了等离子体中的电磁传播和电子密度变化,得到了电子的有效能量和增益。

Electron trapping and field propagation in laser-plasma interaction with density transition
This paper investigates that by using a new electron density transition in plasma, the wave breaking threshold was reduced and transversely electron injection into the acceleration phase of the wake field was increased. Numerical results identify that injected electron bunch causes to modification of the wake field. By optimization of transient length and injected charge of electron, electromagnetic propagation and electron density variation in plasma has been evaluated and the efficient energy and gain of electrons have been obtained.
