C-band high-power multi-beam klystron with reverse permanent magnet

  • 摘要: 反转永磁聚焦C波段高功率多注速调管作为加速器系统的功率源,具有脉冲输出功率高、平均功率大、寿命长的优势,在工业辐照、放射治疗、无损检测等领域具有广阔的应用前景。设计并研发了一种可用于加速器系统的反转永磁聚焦C波段高功率多注速调管。其电子光学系统采用多电子注、周期反转永磁聚焦技术,高频系统工作在TM220高次模式、多腔参差调谐,散热采用水冷方式。通过计算确定了结构参数,研制出速调管样管,通过测试,获得了大于3 MW的峰值输出功率,和计算结果相吻合。
