Demonstration of multi-pulse x-ray generation via laser-compton scattering using pulsed-laser super-cavity

A compact and high quality x-ray source is required for various field, such as medical diagnosis, drug manifacturing and biological sciences. Laser-Compton based x-ray source that consist of a compact electron storage ring and a pulsed-laser super-cavity is one of the solutions of a compact x-ray source. Pulsed-laser super-cavity has been developed at Waseda university for a compact high brightness x-ray source. The pulsed-laser super-cavity enables to make high peak power and small waist laser at the collision point with the electron beam. 357MHz mode-locked Nd:VAN laser pulses can be stacked stably in a 420mm long Fabry-Perot cavity with "burst mode", which means stacking of electron beam synchronized amplified pulses in our R& D. In view of this successful result, we have started an X-ray generation experiment using a super-cavity and a multi-bunch electron beam at KEK-LUCX. Recently, the demonstration experiment between the burst mode pulsedlaser super-cavity and the 100 bunch multi-bunch electron beam is successfully performed. Development of the supercavity and the experimental results of X-ray generationwill be presented at the conference.
