| WEPNEC25 | Research on Alkali Antimonide Photocathode Fabrication Recipe at PKU | 120 |

| Low emittance, high QE and long lifetime photocathode is widely studied for X-ray Free Electron Laser (XFEL)and Energy Recovery Linacs (ERL) applications. A deposition system for alkali antimonide photocathode (K2CsSb, Cs3Sb etc.) is being commissioned at Peking University. In this paper, we present our experimental results on alkali antimonide photocathode with this deposition system. We successfully fabricated Cs3Sb photocathode on oxygen free copper, p-type Si (100) and Mo substrates with QE of 1.4%, 2.6% and 2.6% respectively. | ||

| Stable operation of 3.5 cell DC-SRF photoinjector has been realized with average beam current of ~1mA at Peking university. A new 1.5 cell DC-SRF photoinjector has been designd and now is being constructed. In this talk we will give a brief introduction on the low emittance simulation of the new photoinjector, which indicates that emittance less than 0.5 um could be achieved at 100 pC bunch charge. Laser shaping, bi-alkali photocathode are all in progress. | ||
