Status of the CompactLight Design Study
/ D'Auria, Gerardo (Sincrotrone Trieste) ; Aicheler, Markus (Helsinki Inst. of Phys.) ; Aksoy, Avni (Ankara U.) ; Alesini, David (Frascati) ; Apsimon, Robert (Cockcroft Inst. Accel. Sci. Tech.) ; Arnesano, Jordan Matias (Rome U.) ; Bellaveglia, Marco (Frascati) ; Bernhard, Axel (KIT, Karlsruhe) ; Bosco, Fabio (Rome U.) ; Buonomo, Bruno (Frascati) et al.
CompactLight (XLS) is an International Collaboration of 24 partners and 5 third parties, funded by the European Union through the Horizon 2020 Research and Innovation Programme. The main goal of the project, which started in January 2018 with a duration of 36 months, is the design of an hard X-ray FEL facility beyond today’s state of the art, using the latest concepts for bright electron photo-injectors, high-gradient accelerating structures, and innovative short-period undulators.

Scaling of Beam Collective Effects with Bunch Charge in the CompactLight Free-Electron Laser
/ Di Mitri, Simone (Sincrotrone Trieste ; Trieste U.) ; Latina, Andrea (CERN) ; Aicheler, Marcus (CERN ; Helsinki U.) ; Aksoy, Avni (Ankara U., Inst. Accel. Technol.) ; Alesini, David (Frascati) ; Burt, Graeme (Lancaster U. (main)) ; Castilla, Alejandro (Lancaster U. (main)) ; Clarke, Jim (Cockcroft Inst. Accel. Sci. Tech.) ; Cortés, Hector Mauricio Castañeda (Cockcroft Inst. Accel. Sci. Tech.) ; Croia, Michele (Frascati) et al.
The CompactLight European consortium is designing a state-of-the-art X-ray free-electron
laser driven by radiofrequency X-band technology. Rooted in experimental data on photo-injector
performance in the recent literature, this study estimates analytically and numerically the performance
of the CompactLight delivery system for bunch charges in the range 75–300 pC. [...]

Development of 36 GHz RF Systems for RF Linearisers

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.

S-Band Transverse Deflecting Structure Design for CompactLight
/ Wu, Xiaowei (CERN) ; Di Mitri, Simone (Sincrotrone Trieste) ; Thompson, Neil (Cockcroft Inst. Accel. Sci. Tech.) ; Wuensch, Walter (CERN)
The CompactLight project is currently developing the design of a next generation hard X-ray FEL facility, which is based on high-gradient X-band (12 GHz) structures. However, to carry out pump-and-probe experiments in the project, two-bunch operation with a spacing of 10 X-band rf cycles is proposed. [...]

High-Gradient Breakdown Studies of an X-Band Accelerating Structure Operated in the Reversed Taper Direction

The results of high-gradient tests of a tapered X-band traveling-wave accelerator structure powered in reversed direction are presented. Powering the tapered structure from the small aperture, normally output, at the end of the structure provides unique conditions for the study of gradient limits. [...]

Analysis and simulation of the "after-pulse" RF breakdown
/ Lin, Xiancai (Tsinghua U., Beijing, Dept. Eng. Phys. ; Tsinghua U., Beijing, KLPRI) ; Chen, Huaibi (Tsinghua U., Beijing, Dept. Eng. Phys. ; Tsinghua U., Beijing, KLPRI) ; Liu, Zening (Tsinghua U., Beijing, Dept. Eng. Phys. ; Tsinghua U., Beijing, KLPRI) ; Shi, Jiaru (Tsinghua U., Beijing, Dept. Eng. Phys. ; Tsinghua U., Beijing, KLPRI) ; Wu, Xiaowei (CERN) ; Zha, Hao (Tsinghua U., Beijing, Dept. Eng. Phys. ; Tsinghua U., Beijing, KLPRI)
During the high power experiment of a single-cell standing-wave accelerating structure, it was observed that many RF breakdowns happen when the field inside cavity is decaying after the input rf pulse is off. The distribution of breakdown timing shows a peak at the moment of RF power switches off. [...]

CompactLight design study
/ D'Auria, Gerardo (Sincrotrone Trieste) ; Aicheler, Markus (U. Helsinki (main)) ; Aksoy, Avni (Ankara U.) ; Alesini, David (Frascati) ; Apsimon, Robert (Lancaster U.) ; Arnesano, Jordan Matias (U.

The H2020 CompactLight Project aims at designing the next generation of compact X-rays Free-Electron Lasers, relying on very high gradient accelerating structures (X-band, 12 GHz), the most advanced concepts for high brightness electron photo injectors, and innovative compact short-period undulators. Compared to existing facilities, the proposed facility will benefit from a lower electron beam energy, due to the enhanced undulators performance, and will be significantly more compact, with a smaller footprint, as a consequence of the lower energy and the high-gradient X-band structures.
