Design of the RF waveguide network for the klystron-based CLIC main linac RF module
/ Wang, P (CERN) ; Capstick, M (CERN) ; Catalan Lasheras, N (CERN) ; Doebert, S (CERN) ; Grudiev, A (CERN) ; Rossi, C (CERN) ; Sanchez, P Morales (CERN) ; Syratchev, I (CERN) ; Wu, X (CERN)
The klystron-based Compact Linear Collider (CLIC) was initially proposed with a low center-of-mass energy of 380 GeV, primarily due to potential cost-effectiveness. To enhance overall cost-efficiency, reliability, and stability, a novel RF module for klystron-based CLIC main linac has been designed and studied. [...]

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. [...]

This article presents the design, construction, and high-power test of two X -band radio frequency (RF) accelerating structures built as part of a collaboration between CERN and the Paul Scherrer Institute (PSI) for the compact linear collider (CLIC) study. The structures are a modified “tuning-free” variant of an existing CERN design and were assembled using Swiss free electron laser (SwissFEL) production methods. [...]

As part of the effort to reduce the energy consumption of large research facilities using accelerators, high efficiency klystrons are being developed by CERN. However, a large fraction of the wall-plug power required to operate these klystrons is used in the focusing magnetic elements around the klystron in the form of normal conducting solenoids. [...]

High-Power Testing Results of X-Band RF-Window and 45 Degrees Spiral Load
/ Boronat, Marça (CERN) ; Bursali, Hikmet (CERN) ; Catalán Lasheras, Nuria (CERN) ; Grudiev, Alexej (CERN) ; McMonagle, Gerard (CERN) ; Syratchev, Igor (CERN)
The X-Band test facilities at CERN have been running for some years now qualifying CLIC structure prototypes, but also developing and testing high power general-purpose X-Band components, used in a wide range of applications. Driven by operational needs, several components have been redesigned and tested aiming to optimize the reliability and the compactness of the full system and therefore enhancing the accessibility of this technology inside and outside CERN.
