Second Generation Wire Development at AMSC

摘要: AMSC has established a Second Generation (2G) High-Temperature Superconductor (HTS) wire manufacturing technology based on the Rolling Assisted Biaxially Textured Substrate and Metal Organic Deposition processes. AMSC's 2G (Amperium) been used by wide range of customers for development testing initial commercial HTS-based applications. Although Amperium properties quantities satisfy requirements these projects, improvements in critical current, field performance, cost are beneficial large-scale military As continues to ramp up, R&D program focused increasing nonmagnetic substrates. The process developed single-coat, 1.2 μm YBCO film transferred production-scale equipment, resulting first wires with currents reaching 500 A/cm-w (77 K, self-field) production length. A substrate, which minimizes ferromagnetic substrate losses ac cable applications, produced lengths demonstrated an wire.
