  1. 236. Auger Electron Spectroscopy and Ar Sputtering for the Determination of Y2O3 Buffer Layer Thickness in REBCO Superconducting Tapes
    Mr Christopher Hopp (Materials Science & Engineering Program, University of Wisconsin-Eau Claire)

    Poster Presentation

    Thanks to recent advances in flux pinning, current-carrying capacity, and conductor geometry, REBCO tapes are being considered more seriously for high-field magnet applications. However, the material remains intrinsically weak to transverse tensile stresses, and the buffer and/or superconducting layer in the tape can delaminate when subject to such stresses. In this work we use Auger Electron...

  2. 272. Commercial fabrication of 2G HTS Roebel cables using the “Punch-and-Coat” approach
    Dr Alexander Molodyk (SuperOx)

    Poster Presentation

    We will present the status of commercial production of 2G HTS Roebel cables along the advanced “Punch-and-Coat” route.

    The “Punch-and-Coat” approach to 2G HTS Roebel cable fabrication was recently developed in collaboration between KIT and SuperOx. The approach is to prepare a meander-shaped strand for Roebel cable by mechanical stamping of silver-finished 2G HTS wire, and then electroplate...

  3. 535. Comparative Study on the effect of Laser Energy Density on YGBCO and HGBCO Thin Film Prepared by PLD

    Poster Presentation

    Y0.5Gd0.5Ba2Cu3O7-σ (YGBCO) and Ho0.5Gd0.5Ba2Cu3O7-σ (HGBCO) targets of similar density are prepared by solid-state reaction method. These targets are used to prepare superconducting thin film respectively using pulsed laser deposition (PLD). During the experiment, we alter laser energy by changing optical lens. X-Ray diffraction (XRD) is adopted to analyze the structure and texture of...

  4. 459. Demonstration of New 3 to 4 mm Thin ReBCO-CORC Wires featuring 300 to 500 A/mm2 at 10T/4.2K
    Tim Mulder (Twente Technical University (NL))
    10/07/2017, 14:00
    Poster Presentation

    Several improvements on ReBCO tape performance made it possible to reduce tape width and thickness thereby enabling the process of making thin CORC based ReBCO wires. A major improvement has been the reduction of the tape’s substrate thickness from 100 via 50 to 30 micron and even more reduction is expected in the years to come, leading to a lower minimum bending radius of ReBCO tapes. The...

  5. 366. Post-Delamination Structural Investigation of REBCO Superconducting Tape
    Tanner Olson (University of Wisconsin-Eau Clarie)
    10/07/2017, 14:00
    Poster Presentation

    Rare-earth cuprate-based (REBCO) superconductors are a family of high-field, high-temperature superconductors fabricated in a tape geometry. The tape structure is composed of a nickel-based Hastelloy substrate base, with oxide buffer layers (to allow for epitaxial growth of the superconductor) and a superconducting film of thickness < 2 μm. The composite is finished with a silver cap layer and...
