    Accelerated coated conductor program at Los Alamos national laboratory

    IEEE Transactions on Appiled Superconductivity, vol. 13, no. 2, pp. 2488-2491

    Abstract anzeigen

    In order to accelerate research and development of coated conductors (CC), a new facility has been developed at Los Alamos National Laboratory (LANL) with labs dedicated to scaled-up fabrication and characterization of CC. These laboratories include facilities for metal tape preparation, ion-beam assisted deposition (IBAD) of template layers, superconductor deposition by laser ablation (PLD), as well as materials characterization including low-temperature transport measurements. The work builds on the prior successes of the LANL CC program, such as the benchmark results of critical currents over 300 A on 1-cm-wide short samples deposited via IBAD and PLD. The new labs have recently been completed and include the ability for reel-to-reel tape processing and characterization. Fabrication of long lengths of tape (>10 m) allow for high-throughput experimentation by linear combinatorial design. This facility is also made to enable collaboration with industrial and other partners.

    Continuous electropolishing of Hastelloy substrates for ion-beam assisted deposition of MgO

    Superconductor Science and Technology, vol. 16, no. 5, pp. 613-616

    Abstract anzeigen

    We demonstrate the applicability of continuous electropolishing for the preparation of metal tapes for ion-beam assisted deposition of MgO for the fabrication of in-plane textured template layers. These templates are used for the fabrication of second generation high temperature superconducting wires utilizing YBa2Cu3O7−δ coatings on metallic substrates. Surface roughness values below 1 nm and local slopes of less than 1° could be achieved with the electropolishing process. Mean surface roughness values are lower with the use of electropolishing and slopes of surface roughness inclines are significantly reduced compared to the best results of mechanical polishing (3.5 nm and 5°, respectively). The cost-effective process of electropolishing shows great promise for the fabrication of second generation high temperature superconducting wire.
