摘要

近年来超短超强激光技术得到了飞速发展,基于激光等离子体尾波场的电子加速及新型辐射源研究得到了世界范围内的广泛关注本报告将对激光尾波加速原理做初步介绍,而后对上海交通大学在激光尾波加速中的高品质电子注入、新型级联加速,基于激光尾波的受控X射线辐射方面的研究工作进行介绍。我们将主要介绍基于离化的尾波电子注入机制,获得超低能散、超低发射度的电子束;介绍基于弯曲等离子体通道的多激光脉冲尾波级联加速,提供面向TeV正负电子对撞机的级联解决方案;介绍基于非线性汤姆逊散射和等离子体通道的X射线辐射,实现对辐射强度及偏振的可控调谐。

The rapid development of ultrashort ultraintense laser technology in recent years leads to big progresses of laser plasma based accelerators and radiation sources around the world. In this report, a short introduction of laser wakefield acceleration (LWFA) will be given. Recent studies on high quality electron injection, new scheme of multi-staged wakefield acceleration and controlled x-ray radiation from LWFA at SJTU will be introduced. Specifically, we will focus on the studies of ionization based high quality electron injection, curved plasma channel based multi-staged LWFA, plasma channel based controlled x-ray radiation, and high order nonlinear Thomson scattering.
