Study of Compton backscattering with relativistic high-intense electron beam and single-pass free electron laser (FEL) is carried out to produce high-brightness short X-ray pulse. The single-pass FEL such as SASE is high power coherent light source and the wavelength of the FEL can be tuned changing magnetic field strength of wiggler or undulator continuously. In our study, the relativistic electron beam is generated using a linear accelerator, which is a driver for the FEL. The electron beam is used for both the Compton backscattering and the generation of SASE light. The preliminary experiment of X-ray generation based on Compton backscattering with high-intensity electron beam and infrared SASE light is planed using the L-band linear accelerator at the Institute of Scientific and Industrial Research (ISIR), Osaka University. We will describe the preliminary experiment and the result of numerical studies.
