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. [...]

A collaboration between DESY, PSI and CERN has developed and built an advanced modular X-band transverse deflection structure (TDS) system with the new feature of providing variable polarization of the deflecting force. The prototype of the novel X-band TDS, the polarizable $X$-band (PolariX) TDS, was fabricated at PSI following the high-precision tuning-free production process developed for the C-band Linac of the SwissFEL project.

Engineering Design of a Multipurpose X-band Accelerating Structure
/ Gudkov, Dmitry (Dubna, JINR) ; Riddone, Germana (CERN) ; Samoshkin, Alexander (Dubna, JINR) ; Zennaro, Riccardo (CERN) ; Dehler, Micha (PSI, Villigen) ; Raguin, Jean-Yves (PSI, Villigen)
Both FEL projects, SwissFEL and Fermi-Elettra each require an X-band RF accelerating structure for optimal bunch compression at the respective injectors. As the CLIC project is pursuing a program for producing and testing the X-band high-gradient RF structures, a collaboration between PSI, Elettra and CERN has been established to build a multipurpose X-band accelerating structure [...]
