High repetition-rate inverse Compton scattering x-ray source driven by a free-electron laser

摘要

We describe a hybrid free-electron laser (FEL)/inverse Compton scattering (ICS) system that can be operated at very high repetition rates and with higher average gamma-ray fluxes than possible from ICS systems driven by J/kHz laser systems. Also, since the FEL system can generate 100 mJ class photon pulses at UV wavelengths, the electron beam energy can be lower than for systems driven with similar to micron wavelength lasers for attaining gamma rays of similar energy.
