Abstract

An 1.6 cell rf-gun system has been installed at Waseda University for the generation of high charge, short pulse and low emittance electron beam. The gun is one of essential component for X-ray generation using inverse Compton scattering between photo electron bunch and laser pulse. An all-solid-state picosecond Nd:YLF laser system has been installed at Waseda University and will be used not only for photo electron generation in the rf-gun but also for collision with the photo electron bunch. The laser system has the frequency conversion section, which is operated to produce the UV (262 nm) using BBO crystals from the amplified fundamental (1047 nm). Extremely stable laser system is required for the generation of high quality electron beam, and the system is essential component for the generation of X-rays through the inverse Compton scattering. Timing and intensity stabilities of laser pulse have been measured using time domain demodulation technique. As the results, timing stability of 0.26 ps against to the local oscillator of rf and intensity stability of 0.11% have been achieved. We have carried out the numerical simulation to calculate the number of photons and the energies of X-rays by changing the crossing angles.
