主　　题：photo-injector photocathode Cs 2 Te quantum efficiency 

摘      要：A cesium telluride （Cs 2 Te） photocathode with a quantum efficiency of 13% at 253.7 nm （radiant incidence 200 μW/cm 2 ） is fabricated by tellurium and cesium vapor deposition onto a stainless-steel substrate. The cesium telluride cathode will be used to provide a high-brightness electron beam source for the 3＋1/2 photo-injector at Peking University. The design of the system, the fabrication procedures and the preliminary experimental results are presented in this paper.
