激光尾波场加速产生低能散高亮度电子束源
Generation of Low-Energy-Spread and High-Brightness Electron Beams via Laser Wakefield Acceleration
摘要
Abstract
Plasma wakefield acceleration driven by ultrashort and ultra-intense laser pulses represents a novel compact scheme of laser-driven electron acceleration,providing new opportunities and pathways for next-generation particle acceleration techniques,as well as for the generation and frontier applications of novel ultrafast particle beams and high-energy radiation sources.Over the past two decades,significant progress has been achieved in laser-wakefield electron acceleration regarding both high-energy gain and beam quality.In particular,breakthroughs have been realized in attaining sub-per-mille energy spread,while beam brightness and application performance have also been enhanced enabling wide applications in cutting-edge interdisciplinary research such as high-energy particle physics,nuclear photonics,material science,and biomedical science.This paper reviews recent advances and future prospects in several frontier topics:the plasma wakefield acceleration and energy chirp control driven by femtosecond intense laser pulses,generation of high-brightness ultrafast electron beams based on the weakly nonlinear laser wakefield,and the achievement of sub-per-mille ultralow energy spread via quasi-linear laser wakefield acceleration.关键词
