Description
Cryogenics is one of the major energy costs in modern SRF accelerators because of the need to lower the operating temperature to 2K. Substituting Nb with a higher critical-temperature superconductor, such as Nb3Sn, allows operations to be moved up to 4.5 K with a reduction in cryogenic costs by a factor of 3. The European collaboration I.FAST, has the ambitious goal of producing the first prototype of 1.3 GHz Nb3Sn on Cu thin-film elliptical cavity. Through the collaboration between 12 different European research institutes, the different R&D activities cover the entire cavity production chain. In this work the main results obtained by the collaboration will be shown, in particular concerning the development of superconductive coatings of Nb3Sn by Magnetron Sputtering. The scalability from small flat samples to elliptical cavity prototypes and the goals of the new European ISAS project will be also discussed.
