摘要
简要介绍了一种W波段分布作用速调管的设计思路、设计方案和模拟结果,并给出了该管的测试结果。该管采用大压缩比圆柱电子枪和永磁聚焦系统,阴极电压17 kV,阴极电流0.78 A;高频系统由5间隙和11间隙(输出腔)的分布作用腔组成,采用长短槽梯形结构。样管实现了脉冲输出功率大于2 kW、带宽500 MHz、增益40 dB、工作比5%等指标。
This paper briefly introduces the design of a W-band extended interaction klystron(EIK),and gives the test results.The high frequency extended interaction circuit consisted of five 5-gap buncher cavities and one 11-gap output cavity which can obtain wider bandwidth.This ladder-type multi-gap cavity circuit is easy to fabricate and supports greater energy margins.Theπ-mode is selected as the operating mode of the 5-gap(or 11-gap)cavities.By now,with an electron beam of 17 kV and 0.78 A,the EIK has achieved a peak output power of 2 kW,bandwidth of500 MHz,gain of 40 dB,and duty cycle of 5%.
