Light sources based on inverse Compton scattering:a review and perspectives
摘要
Abstract
Inverse Compton scattering(ICS)is a fundamental physical process involving an energy exchange between photons and electrons.ICS light sources,generated by collision between relativistic electron beams and intense laser pulses,offer high-brightness,energy-tunable,and short-pulsed X-rays or gamma-rays,which are supporting diverse scientific research and applications worldwide today.This paper aims to review the current technological status and future development prospects of ICS light sources,which are categorized into three evolutionary phases.The first phase,incoherent Inverse Compton scattering(InICS),is a mature foundational technology for most existing ICS light sources and has been widely applied in various fields.The second phase,coherent inverse Compton scattering(CoICS),enhances radiation brightness and beam quality through coherent interactions between electron and photon beams,with key technical approaches including periodic photon structures and periodic electron structures.The third phase,stimulated inverse Compton scattering(StICS),achieves nonlinear enhancement of scattering intensity via stimulated emission amplification,analogous to free-electron lasers(FEL),and holds promise for ultra-high brightness radiation.In this paper,a systematic analysis of the principles,key steps,and technical challenges of each phase is provided.Furthermore,numerical simulations demonstrate that periodic electron structures induced by optical fields can achieve significant coherent enhancement,producing high-quality beams with smaller energy spread and angular divergence.It is envisioned that with advancements in high-intensity short-pulse laser technology,flying focus,and high-current short-pulse electron acceleration,CoICS and StICS are expected to develop rapidly,providing superior brightness and beam quality in the ultraviolet to soft X-ray bands,and opening new avenues for related scientific research and industrial applications.关键词
