Generation of X-ray by back-Compton scattering

The high-bright X-ray can be generated by the back-Compton scattering through the laser with electron beam, and the wavelength is tunable by changing the electron energy. Because of the low scattering chance of the scattering photon with the electron, it is difficult to acquire the high-bright radiation. The high power density laser and the high-bright electron beam is required to obtain the high-bright radiation. In the experiment, the electron beam of CAEP RF photoinjector together with 30MeV linac and the high power density laser in Nd:YAG laser cavity will be used, the radiation wavelength is 0.07 0.14nm, the radiation ability expected to be about 2.5 1011 photons per second, and the radiation wavelength can be tuned by changing the electron energy.
