  Recent progress on plasma based acceleration at Tsinghua University will be presented. On the theory and simulation part, several ideas on how to obtain high quality electron beams with extremely high brightness through wakefield acceleration will be discussed in details,including two recently published works based on ionization injection method(PRL 111,015003,2013; PRL 112,035003,2014); On the experiment part, our recent results of high quality 20-30MeV electron beams with very low energy spread, with minimal absolute energy spread of 0.18MeV RMS and relative energy spread 0.8% RMS, will be presented. The latest results on the generation of 300-430MeV high quality electron beams (2-5% energy spread) using a 50TW laser at NCU will also be discussed.

  Due to the great applications of ultrafast X-ray in detecting the micro-world, the X-ray sources develop rapidly. One of X-ray sources named Laser-Electron X-ray Machine (LEXM) based on the Inverse Compton Scattering of optical cavity is very promising. Accelerator Lab of Tsinghua University has finished the basic proto-type design. This paper compares the different kinds of X-ray source, such as SR, FEL, X-ray tubes and LEXM. And this paper optimizes the optical lengths of four mirrors structure optical cavity and analysis the mechanical stabilities of two mirrors and four mirrors structure optical cavity. According to the simulation results, we choose the four mirrors structure optical cavity.

  In the last three years, we have successfully generated high quality hard X-ray pulse at Tsinghua Thomson scattering X-ray source. The X-ray parameters, such as flux, beam profile, energy and spectrum, were measured successfully. One of the most interesting applications, x-ray phase contrast imaging, has also demonstrated on this facility. In this paper, we will show the recent progress of this facility in detail.
