"DC-SRF photoinjector at Peking Accelerator 

Jiankui Hao 
Peking University 

DC-SRF electron injector, which combines a DC Pierce gun and a 3.5-cell 1.3 GHz superconducting cavity in a cryomodule , has been developed at Peking University. Based on the improvements of beam line, LLRF system and 2K cryogenic system, stable operation of the DC-SRF injector has been carried out recently. Electron beams with 3.4 MeV energy and the currents of ~1mA in a macro-pulse mode was obtained. As the first application of this DC-SRF injector, THz radiation produced with a 10 period undulator was detected. As another application, ultra fast electron diffraction (UED) was successfully carried out with DC-SRF injector.
