In this talk we will remind the baseline configuration of the SRF system for FCC-ee (booster and collider rings).
We will also present new SRF cavity designs like spoke cavities and coaxial resonators, which have been explored recently and compared to the baseline design.
A new elliptical 2-cell cavity configuration equipped with slotted waveguides, called SWELL cavity is finally...
The Hydroforming process is a well-established acquaintance in the SRF world. Recently, progress has been performed in the ability to better tune such process; namely through enhanced quality of the inherent fabrication processes, and through the implementation of large deformation numerical analyses for a finer definition of process parameters.
Presentation will focus on the ongoing analyses...
The innovative concept of two-stage multi-beam Klystron has been previously investigated and studied in a 1GHz 20MW Klystron for CLIC. This technology utilizes low voltage electron beam in its first stage to compress the tube length and DC post acceleration in the 2nd stage to ensure ultra-high efficiency. It is very practical for the compact design at low frequency (UHF and L-band), high...
Overview of the various challenges regarding the construction of very high power Fundamental Power Couplers will be presented.
Superconducting radio frequency (SRF) cavities with performance beyond the fundamental limits of bulk niobium require coating technologies. Multilayer systems with alternating thin films of superconducting and insulating material promise to boost the performance in terms of maximum accelerating gradient and surface resistance. Futhermore, the insulating layer prevents full penetration of...
Thin film coated superconducting radiofrequency (SRF) accelerating cavities are among the most promising technologies to provide a cost efficient accelerator in the framework of the Future Circular Collider (FCC) study.
We will give a broad overview of the currently on-going R&D topics such as the optimization of surface treatment by electropolishing, the elaboration of niobium thin films by...
Among the bases that substantiate the feasibility of the FCC, the RF characterization of scaled versions of accelerating cavities becomes one of the major milestones within the project timeline. In particular, niobium thin film cavity deposition is regarded as the main alternative to the bulk (for example, this is the technology used in the HIE-ISOLDE QWRs at CERN), leveraging the heat...
