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. [...]

Development of 36 GHz RF Systems for RF Linearisers / Castilla, Alejandro (CERN ; Cockcroft Inst. Accel. Sci. Tech. ; Lancaster U.) ; Behtouei, Mostafa (Frascati) ; Burt, Graeme (Lancaster U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Cai, Jinchi (CERN ; Cockcroft Inst. Accel. Sci.

As part of the deign studies, the CompactLight project plans to use an injector in the C-band. Which constitutes a particular complication for the harmonic system in charge of linearising the beam’s phase space, since it means its operation frequency could be higher than the standard X-band RF technologies.

Design Study of X-band High Efficiency Klystrons for CLIC / Cai, Jinchi (Lancaster U. ; CERN) ; Syratchev, Igor (CERN)
The design of two X-band high efficiency (HE) Klystrons are presented in this paper. Based on Core Oscillation Method (COM) and coupled-cell output structure topology, 8MW Klystron for Xbox test stand can yield 58% output efficiency with beam perveance of 1.6uP. [...]

Numerical Analysis of Resonant Multipolar Instabilities in High Power Klystrons / Cai, Jinchi (Lancaster U.) ; Syratchev, Igor (CERN) ; Burt, Graeme (Lancaster U.)
The monopole monotron instability is a well-known phenomenon in linear beam devices. In recent development of a high-efficiency 50-MW X-band klystron, such instabilities were found and mitigated in a special second-harmonic multicell cavities triplet that is used to improve the klystron's performance.

Accurate Modeling of Monotron Oscillations in Small- and Large-Signal Regimes / Cai, Jinchi (Lancaster U. (main)) ; Syratchev, Igor (CERN) ; Burt, Graeme (Lancaster U. (main))
In Klystron amplifiers, monotron oscillations may cause unacceptable beam instabilities. For facilitating fast and accurate analysis of such processes, rather than performing time-consuming particle-in-cell simulations, the theory of the monotron oscillations has been further developed for the small- and large-signal regimes and implemented into the klystron computer code KlyC. This development includes full considerations of the spacecharge effects, relativistic effects and can operate with arbitrary field distributions of the resonant mode. [...]

Modeling and Technical Design Study of Two-Stage Multibeam Klystron for CLIC / Cai, Jinchi (Lancaster U. (main)) ; Syratchev, Igor (CERN)
The RF power production efficiency is one of the major concerns in the 3-TeV Compact Linear Collider (CLIC) Drive Beam Accelerator, as it is responsible for almost 50% of the entire accelerator complex power consumption. The klystron technology with dc post acceleration of the prebunched beam was reconsidered recently, as an attempt to develop a technological solution for the high efficiency, high power L-band multibeam klystrons (MBKs). [...]
