摘　　要：随着雷达技术的发展,速调管平均功率越来越高。在速调管工作过程中,将有一部分电子打在高频系统上产生热量。高频冷却系统的设计直接影响到速调管高平均功率的实现,本文对反转永磁聚焦系统的S波段多注速调管进行分析,研究了提高散热能力的途径及可采用的措施,对收集极磁屏的水冷结构进行了改进,对改进后结构进行了热分析和磁分析,证明了冷却方案的可行性。With the development of radar technology,the average power of klystron is becoming higher and higher.During the operation of klystron,some electrons hit the cavity and result in temperature rising.The cooling structure of klystron RF circuit restricts the increase of average power.A S-band multi-beam klystron with periodic reverse permanent magnetic focusing system is shown in the paper.The methods of increasing cooling efficiency are investigated,and a cooling structure of collector magnetic screen is brought forward and proved.
