Narrow-band GeV photons generated from an X-ray free-electron laser oscillator

Hajima, Ryoichi; Fujiwara, Mamoru

We propose a scheme to generate narrow-bandwidth GeV photons, -rays, via Compton scattering of hard X-ray photons in an X-ray free-electron laser oscillator. Generated -rays show a narrow-bandwidth spectrum with a sharp peak, 0.1% (FWHM), due to large momentum transfer from electrons to photons. Such -rays will be a unique probe for studying hadron physics. Features of the -ray source, flux, spectrum, polarization, tunability and energy resolution are discussed.
