Abstract：
The X-ray source based on Thomson scattering of ultrashort laser pulse with a relativistic electron beam is a means of generating tunable, narrow bandwidth, ultrashort pulse of hard X-rays. Such a sub-picosecond hard X-ray source is proposed at Tsinghua University, and a preliminary experiment with a 16MeV Backward Traveling electron linac and a 1.5J, 6ns Q-switched Nd:YAG laser is carried out first. A 6 ns pulse X-ray with a peak energy of 4.6 keV and an intensity of 1.7$\times 10^4$ per pulse was generated successfully in the experiment. The experimental setup, result and discussion are reported in this paper.
