Practical superconductor development for electrical power applications -- Annual report for FY 1999

Development of useful high-Tc superconductors requires synthesis of superconducting compounds; fabrication of wires, tapes, and films from these compounds; production of composite structures that incorporate stabilizers or insulators; and design and testing of efficient components. This report describes FY 1998 technical progress of research and development efforts aimed at producing superconducting components in the Bi(Pb)SrCaCu and YBaCu oxide systems. Topics discussed are synthesis and heat treatment of high-Tc superconductors, formation of monolithic and composite conductors, characterization of structures and superconducting and mechanical properties, and fabrication and testing of prototype components. Collaborations with industry and academia are documented.
