摘要: 介绍了花瓣形辐照加速器NB100高频系统整体方案和设计过程，如输入组件采用磁耦合设计、功率源与加速腔间采用同轴线连接、隔离窗选用平板窗等；给出了耦合环的最终设计数据与图形。高频系统投入使用后，通过初步测试，得到了驻波比小于1.1情况下，入射功率连续100 kW、脉冲250 kW的结果，证实了高频系统设计的合理性。Abstract: The paper introduces the RF system overall solutions and design process for the petal- shaped irradiation accelerator NB100, such as the magnetic coupling design of the input components, the mode connected by coaxial transmission line between RF power source and accelerating cavity, the choice of flat window as the isolation window. Final design data and graphics for coupling loop are also included. With the RF system being put into use, the initial test shows that, the continuous input power is 100 kW and the pulse power is 250 kW when the standing wave ratio is less than 1.1. The rationality of the RF system design scheme is confirmed.
