    Other superconducting materials beyond niobium
    Nb3Sn-coated Nb SRF cavities are studied due to their potential of providing a higher accelerating gradient over Nb SRF cavities. Magnetron sputtering can be a feasible alternative to conventional tin vapor diffusion process to fabricate Nb3Sn for SRF cavities. By depositing Nb and Sn layers separately and annealing afterward, the stoichiometry of the coated films can be controlled to create...

    Other superconducting materials beyond niobium
    Nb3Sn-coated SRF cavities can potentially achieve superior performance in terms of quality factor, accelerating gradient, and operating temperature. Tin vapor diffusion process of Nb3Sn coating on Nb is a simple, yet efficacious technique to fabricate Nb3Sn-coated SRF cavities. The process comprises two¬ steps: “nucleation” followed by “deposition”. The crucible with Sn/SnCl2 and the substrate...

    Other superconducting materials beyond niobium
    Nb3Sn alloy is a type II superconductor with maximum Tc of 18 K and predicted superheating field of 400 mT and potentially may offer improvements in both cryogenic efficiency and maximum accelerating field. Hence, Nb3Sn thin film can be an alternative superconducting coating either as a single or multilayer for SRF cavity production. Nb3Sn has been deposited from stoichiometric alloy target...

    Other superconducting materials beyond niobium
    Superconducting radio frequency (SRF) cavities, made of niobium films on copper (Nb/Cu), are currently employed for a large variety of particle accelerators. At the same time, the Nb/Cu technology, being very cost effective, also represents one of the main options for upcoming machines like the future circular collider (FCC). While research and development continue on the Nb/Cu...
