中文摘要：
针对在高频率、高效率、低磁场以及低电压工作方面具有自身独特优势的扩展互作用速调管（EIK）谐振系统进行了研究,主要目的是在保持其已有优势的情况下增加带宽。在EIK谐振系统研究的基础上,通过优化慢波结构和谐振腔来达到增加其带宽的目的。在此基础上完成了带宽为2.8 GHz,工作在2π模式的宽带EIK谐振系统设计。
英文摘要：
The resonant system of the W-band wideband extended interaction klystron （EIK） was modeled, simulat- ed, and re-designed to widen the bandwidth while maintaining the existing advantages, such as the high operating fre- quency, high efficiency, low magnetic field, and low operating voltage. The bandwidth can be considerably increased by optimizing the design of the resonant cavity and the slow wave structure. We found that an increase of the bandwidth af- fects the coupling impedance of the slow wave structure and the total efficiency. Based on the calculated results, a proto- typed, W-band wideband EIK resonant system with a band width of 2.8 GHz, operating in 2π mode was designed, fabri- cated, and to be testes soon.
