accelerating,cavities,High Efficiency,klystron,output

The CEPC PROJECT in china requests new type of RF sources for the high power conditioning of the accelerating cavites.We are working on the development of a new kind of high efficiency CW klystron to fulfill this need,In this paper,with the help of a Three-Dimensinonal Particle in Cell simulation,design and optimization geometry of the structure is performed. In present work,the output CW power 850kW is achieved.the efficiency reaches 75%,whichi is operating at beam voltage and beam current is 80kV and 14A,respectively.
