Exploratory Study on High-Efficiency High-Power W-Band Klystron Based on Kladistron Technology / Cai, J C (UESTC, Chengdu) ; Su, Z X (UESTC, Chengdu) ; Peauger, F (CERN) ; Xu, J (UESTC, Chengdu) ; Burt, G (Lancaster U. (main)) ; Yue, L N (UESTC, Chengdu) ; Yin, H R (UESTC, Chengdu) ; Zhao, G Q (UESTC, Chengdu) ; Xiang, W W (UESTC, Chengdu) ; Wei, Y Y (UESTC, Chengdu)
To achieve tens of kilowatt (kW) output power, ${W}$ -band klystron usually employs a large beam tunnel to accommodate high current. The deteriorated effective impedance of the cavity could be reenhanced by adopting extended interaction (EI) cavities. [...]

KlyC expansion: Traveling wave module in Klystron simulation code / Cai, Jinchi (UESTC, Chengdu) ; Li, Wei (UESTC, Chengdu) ; Su, Zixuan (UESTC, Chengdu) ; Xu, Jin (UESTC, Chengdu) ; Yue, Linna (UESTC, Chengdu) ; Yin, Hairong (UESTC, Chengdu) ; Yin, Pengcheng (UESTC, Chengdu) ; Zhao, Guoqing (UESTC, Chengdu) ; Wang, Wenxiang (UESTC, Chengdu) ; Wei, Yanyu (UESTC, Chengdu) et al.
Since Klystron simulation code KlyC was released in 2017, it has been used for the design of series of high efficiency (HE) Klystron projects. Lots of new features such as coupling mode analysis, monotron diagnosis and complete small signal theory have been implemented into KlyC to facilitate sophisticated Klystron design. [...]

Beam Optics Study on a Two-Stage Multibeam Klystron for the Future Circular Collider / Cai, Jinchi (UESTC, Chengdu) ; Nisa, Zaib un (CERN) ; Syratchev, Igor (CERN) ; Burt, Graeme (Lancaster U.)
The two-stage (TS) multibeam klystron (MBK) technology has recently attracted significant research attention due to its compactness and high-efficiency (HE) performance. However, there is still a lack of scientific research on the beam optics for such microwave power sources integrated with a postacceleration (PA) gap. [...]

Scaling Procedures and Post-Optimization for the Design of High-Efficiency Klystrons / Cai, Jinchi (CERN) ; Syratchev, Igor (CERN) ; Lui, Zening (Tsinghua U., Beijing)
A semianalytical parametric scaling procedure (PSP) for klystron design has been developed. The PSP allows existing klystron designs to be scaled to different operating frequencies, beam power, and perveance, while maintaining the electron bunching and deceleration processes. [...]

Validation of high efficiency klystron technology / Alonso Arias, Paz (CERN) ; Chauchet, Alan (CERN) ; Marrelli, Chiara (Lund U.) ; Syratchev, Igor (CERN) ; Webber, Maggie (CERN) ; Boronat, Marça (CERN) ; Jones, Matthew (Daresbury) ; Catalan-Lasheras, Nuria (CERN) ; González-Antón, Sergio (CERN) ; Zaib, Un Nisa (Beijing, GUCAS)
The delivery of high RF power---from hundreds of kW to MW---by klystrons, is linked with a high overall energy consumption. A research programme led by CERN in collaboration with the industry is being conducted to understand what limits klystron efficiency and how to develop high-efficiency klystrons. [...]
