X-ray Generation by Inverse Compton Scattering Using Electron Beam Produced by Laser Wakefield Acceleration

Abstract

An inverse Compton scattering (ICS) X-ray source, which is produced by the scattering of a laser pulse with a high-energy electron beam, is a new type of a high-energy X-ray source coupled with a highpower laser and an electron accelerator. Recently, X-ray generation by ICS using an ultrashort electron pulse produced by laser wakefield acceleration (LWFA) has been conducted to realize all-optical, compact, ultrashort X-ray sources. We review the present status and the future prospects of ICS X-ray sources based on LWFA.
