Zusammenfassung: | Magnesium diboride (MgB 2 ) thin films are a potential alternative to low-temperature superconductors (LTS) due to a higher critical temperature ( Tc ) of approximately 39 K. The reactive evaporation deposition technique also affords relatively simple growth of MgB 2 films on flexible substrates compared to high-temperature superconductors (HTS). We have designed and fabricated a cable architecture consisting of MgB 2 traces on flexible yttria-stabilized zirconia (YSZ) compatible with commercially available connectors or direct wirebonds. Key performance metrics such as critical current density ( Jc ) and Tc are measured and compared. We discuss thermal conductivity and passivation schemes for these cables. |
