基于预等离子体通道的小型化高能激光尾波场电子加速器
Compact High Energy Laser-Wakefield Accelerator Based on Preformed Plasma Channel
摘要
激光等离子体尾波加速是一种重要的电子加速机制，其加速梯度可达到100 GeV/m。但如果不加以控制，则加速距离被限制在一个瑞利距离以内。而预等离子体通道的引入，使得加速距离可大大加长，目前已经可以在厘米尺度内获得吉电子伏特的高能电子。这将有助于得到更小的高能物理实验装置以及超亮的自由电子激光器。
Abstract
Laser-wakefield accelerator, in which the electric field gradient can reach 100 GeV/m, offers the potential of high energy electron accelerator. Without any form of guiding, the laser-plasma interaction length is limited to the order of Rayleigh distance. Based on the preformed plasma channel, the interaction length is lengthened to the centimeter scale and GeV e-beams can be obtained. This offers the prospect of compact setup for high energy physics and free electron lasers with unprecedented brilliance.
