Description
Generation of high-energy photons via collision of relativistic
electron and laser beams is known as inverse Compton scattering
or laser Compton scattering.
Compton sources, photon sources based on Compton scattering,
have been developed in the world
to realize high-flux/high-brightness X-ray/gamma-ray sources
and exploit applications with energy-tunable and narrow-bandwidth photon
beams from these sources.
Recent progress of electron accelerator and laser technologies
will open a new era in Compton sources.
An electron beam of small emittance and high-average current contributes
to improving spectral brightness of Compton scattered photons.
Flux of generating photons is also increased by a high-power
laser together with apparatus such as laser enhancement cavity.
We overview the current status of Compton sources including an
experiment carried out at the Compact ERL, which was the first
demonstration of Compton scattering by combination of an energy-recovery
linac and a laser enhancement cavity.
Future prospect of Compton sources and their applications
is also discussed.
