A 50MeV electron linac have been developed in Tsinghua University, which consists of a 1.6Cell photocathode rf gun, a 3-meter s-band SLAC type traveling wave (TW) accelerating structure an a s-band TW buncher. The photocathode rf gun is working at 120MV/m, 2856MHz, with very small dark current. The emittance of the electron beam is less than 1mm.mrad at 500pC, and 0.5mm.mrad at 200pC. The linac is designed for Tsinghua Thomson scattering X-ray source (TTX), and 2x107 photon/bunch at 50keV has been got and some application experiments with the x-ray have been carried out. The new photocathode rf gun and x-band high gradient accelerating structure development will also be introducted in this talk.
