  • Projects

    • Novel SOL GEL Technology for long lenght superconductivity coated tapes.
    • European Project (7PM): European Development of Superconducting Tapes (Eurotapes)


      High current coated conductors (CC´s) have high potential for developing electrical power applications and very high field magnets. The key issues for market success are low cost robust processes, high performance and a reliable manufacturing methodology for long length conductors. In recent years EU researchers and companies have made substantial progress towards these goals, based on vacuum (PLD) and chemical deposition (CSD) methods towards nanostructuring of films. This provides a unique opportunity for Europe to integrate these advances in high performance conductors.

      The consortium consists of 20 partners from 8 member states – 6 universities (Cambridge, UK; Antwerp, B, UAB Barcelona, ES, TU Cluj, RO, U. Ghent, BE and TU Wien, A), 5 institutes (CSIC-ICMAB, E, ENEA, I, IEE, SK,Inst. Neel-CNRS, F, and IFW, D), 1 technological center (LEITAT, ES) and 8 industrial companies (Bruker, D, Evico, D, Theva, D, Nexans GmbH, D, Percotech, D, Nexans SA, F, La Farga, ES and Oxolutia, ES)

      This project has received funding from the European Union's Seventh Programme for research, technological development and demonstration under grant agreement No 280432.
