Description
The SWELL and WOW cavities are novel superconducting RF (SRF) concepts developed within the framework of the FCC study, specifically designed for high beam current acceleration and deflection. Exploiting niobium thin film technology on copper substrates, these cavities offer significant advantages in terms of cost efficiency and performance robustness. This presentation summarizes preliminary RF test results conducted at 4.5 K and 2 K in a vertical cryostat on two prototypes fabricated and niobium-coated at CERN. The achieved performance in terms of 𝑄0 and RF voltage, current limitations, and future prospects are discussed.
