  • Low ac loss filamentary coated superconductors
    Patent number: 7496390
    Abstract: An article having low ac loss includes an elongated substrate having a length and a width; and a plurality of filaments comprising an oxide superconductor extending substantially along the length of the elongated substrate and spaced apart from one other filaments across the width of the elongated substrate, wherein at least one filament crosses over at least one other filament such that the at least one filament occupies a first position across the width of the elongated substrate before the crossover and a second position across the width of the elongated substrate after crossover.
    Type: Grant
    Filed: September 29, 2004
    Date of Patent: February 24, 2009
    Assignee: American Superconductor Corporation
    Inventors: Cornelis Leo Hans Thieme, Martin W. Rupich, John D. Scudiere, Oleg A. Chevtchenko
