摘　　要：The RF system for the Beijing Electron Positron Collider Upgrade(BEPCⅡ)Project had been working since Nov,2006.It consists of 3 subsystems including the superconducting cavity,the klystron and the low level RF system.Compared with the former RF system,the operating frequency has been changed from 200MHz to 499.8MHz, and the superconducting cavity has been used to replace the normal cavity.Up to now,the RF system performance is good and achieves the designed target.北京正负电子对撞机二期(BEPCⅡ)的高频系统已于2006年11月投入运行,它包括了3个子系统:超导腔、发射机和低电平控制系统.与以前的高频系统相比,工作频率由200MHz变为499.8MHz,超导腔取代了常温腔.在过去一年的运行中,高频系统表现良好,达到了设计指标.
