英文摘要	We present the first phase R&D for the 800 kW cw, 650MHz klystron for the future circular electron-positron collider (CEPC) project in China. The CEPC requires 192 klystrons and it is desired to be designed in the Institute of High Energy Physics, CAS, and manufactured domestically. Therefore, we present the manufacturing schedule of this project; the three-stage development from the beam test tube to the klystron having a high efficiency structure. Design of the beam test tube that comprises electron gun and collector is presented. First, gun simulation having a modulating anode is performed using DGUN software. The uniform beam trajectories with a beam perveance of 0.64 mu A/V-3/2 are simulated. We employ a Ba-dispenser cathode of radius 35mm with phi 10 hole at the center and obtain a current density on cathode less than 0.45 A/cm(2). The beam trajectories are also simulated over beam test tube of length about 2m with a magnetic field of 213 Gauss. Thermal analysis of the collector is performed using the ANSIS-CFX code and hence the cooling structure is determined. Mechanical design is almost carried out and it is in manufacturing stage.
