摘　　要：北京正负电子对撞机升级改造工程(BEPCⅡ)将采用频率为500MHz的高频系统取代现有的 200MHz高频系统,其对撞模式的柬流流强设计指标为0．91A,这对高频功率源提出了很高的要求．本文根据BEPCⅡ总体指标和高频系统的相关技术参数,提出了其高频功率源的总体布局、技术指标和设计要求以及配套设施的设计方案,在此基础上我们已完成了第一套高频功率源的安装和调试,并通过了专项和整机的测试验收．For the sake of acquiring the shorter beam bunch length a 500MHz RF system will be adopted in Beijing Electron-Positron Collider Upgrade （BEPCⅡ） project to replace the existing 200MHz RF system. The designed beam current of BEPCⅡ is 0.91A which put forward high requirements to the parameters of RF power source. According to the BEPCⅡ general goals and the related requirements with RF system we completed the BEPCⅡ RF power source layout and all technical designs including the parameters for the transmitters and the circulators, completed the designs of all auxiliary systems. Based on these designs, the first BEPCⅡ RF power source including the transmitter and the circulator as well as the auxiliary systems have been established and passed the acceptance test.
