本文讨论了大功率、高增益、宽频带大功率速调管的设计和制造,还采用小信号增益和大信号效率计算程序,对宽频带速调管的群聚段进行了设计。当小信号增益大于50dB时,7腔速调管的群聚频宽宽于10％,8腔速调管的群聚频宽可达10—15％ 给出了两类宽频带输出电路,即滤波器型输出电路和重叠模双间隙腔输出电路的设计方法和测试结果,结果表明:前一种输出电路的频宽可达7.5—10％,后一种输出电路的频宽可达10—15％。 研制了两种类型速调管,采用滤波器型输出段的速调管的性能达到:1dB等激励频宽为7.5％,效率为38％,饱和增益大于43dB,输出功率大于2.5MW。采用双间隙腔输出段的速调管的1dB等激励频宽迟10％,工作稳定。
This article discusses the design and manufacture of high-power, high-gain, broadband high-power klystron tubes, and also designs the cluster section of the broadband klystron using a small-signal gain and large-signal efficiency calculation program. When the small signal gain is more than 50dB, the bandwidth of the 7-cavity klystron is more than 10% and the cluster bandwidth of the 8-klystron is 10-15%. Two types of broadband output circuits are given Filter-type output circuit and overlap mode double gap cavity output circuit design method and test results show that: the former output circuit bandwidth up to 7.5-10%, the latter output circuit bandwidth up to 10- 15%. Two types of klys tubes were developed. The performance of the klystron tube with the filter type output section is as follows: the excitation bandwidth of 7.5dB, such as 1dB, the efficiency of 38%, the saturation gain of more than 43dB and the output power of more than 2.5MW. Double gap cavity output section of the klystron 1dB and other incentive bandwidth delay of 10%, stable.
