A 40MEV ELECTRON SOURCE WITH A PHOTOCATHODE FOR X-RAY GENERATION THROUGH LASER-COMPTON SCATTERING

We have been developing a short pulse x-ray generation system based on Laser-Compton scattering. A stable electron source with 40MeV energy was developed to generate 30keV X-ray pulses in a head-on collision configuration. Electron energy of 38MeV with 0.2% bandwidth (FWHM) was measured by a bending magnet. Normalized emittance was measured to be 3.5 mm.mrad (rms).
