“…Given the high achievable accelerating gradient, the technology is also attractive in applications where the accelerator size and the associated infrastructural costs are key constraints such as compact photon sources, future FELs, and radiotherapy facilities. Two examples where the use of X-band cavities is already planned are the Smart*Light project [58], a compact and transportable hard X-ray inverse Compton scattering source, and the CompactLight study [59], a collaboration established to design a next-generation FEL with a lower cost and size than existing facilities. Additionally, the use of very highenergy electron (VHEE) beams in the range 50-250 MeV has recently been studied as a potential radiotherapy option for the treatment of deep-seated tumors, and this is another application to which the technology is well-suited [8,[60][61][62].…”

This paper 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. The purpose of the study is twofold; the first objective is to validate the RF properties and high-power performance of the tuning-free, vacuum brazed PSI technology. The second objective is to study the structures' high-gradient behaviour to provide insight into the breakdown and conditioning phenomena as they apply to high-field devices in general. Low-power RF measurements showed that the structure field profiles were close to the design values, and both structures were conditioned to accelerating gradients in excess of 100 MV/m in CERN's high-gradient test facility. Measurements performed during the second structure test suggest that the BDR scales strongly with the accelerating gradient, with the best fit being a power law relation with an exponent of 31.14. In both cases, the test results indicate that stable, high-gradient operation is possible with tuning-free, vacuum brazed structures of this kind.

“…Nowadays, most XFEL injectors operates with 0.25 nC with emittance below 0.4 µm [8][9][10]. Even lower beam emittance of 0.1 µm at 100 pC is persued by the development of XFEL with lower linac energy, such as compact XFELs and XFELs based on the continuous wave superconducting linac [11][12][13]. The XFEL developments drive the photoinjector transverse brightness B 4D up by a factor 10 in the last decades.…”
