摘要

近年來超短超強激光技術得到了飛速發展,基於激光等離子體尾波場的電子加速及新型輻射源研究得到了世界範圍內的廣泛關注本報告將對激光尾波加速原理做初步介紹,而後對上海交通大學在激光尾波加速中的高品質電子注入、新型級聯加速,基於激光尾波的受控X射線輻射方麵的研究工作進行介紹。我們將主要介紹基於離化的尾波電子注入機製,獲得超低能散、超低發射度的電子束;介紹基於彎曲等離子體通道的多激光脈衝尾波級聯加速,提供麵向TeV正負電子對撞機的級聯解決方案;介紹基於非線性湯姆遜散射和等離子體通道的X射線輻射,實現對輻射強度及偏振的可控調諧。

Therapiddevelopment of ultrashort ultraintense laser technology in recent years leads to big progresses of laser plasma based accelerators and radiation sourcesaroundthe 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, wewillfocuson 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.
