We are ongoing R&D of ultra-fine MgB2 superconducting wires having a very small diameter much less than a human hair. These ultra-fine MgB2 wires could be bundled and fabricated easily into stranded cables for increasing the current capacity. In principle, the bending strain decreases with decreasing the wire diameter as well as the hysteresis loss. The stranded cables made by these...
Because of the tape architecture of the REBCO coated conductors (CCs), it is crucial to grasp the size of the tape width and its variation along the length for the design of magnets or coils. Geometrical size can be measured relatively easily by such techniques as laser microscopy or optical microscopy, however, the electromagnetic tape width, at where the superconducting current can flow, is...
The development of ultrahigh power density rotating machines is a research priority identified by electric aircraft programs worldwide, including ARPA-E, NASA, Airbus, and many others. There are many high field DC and AC magnet applications of such wires. One of the most important building blocks for these applications is the electric wire conductors. A complete scan of the resistivity of...
Iron-based superconductors (IBS) are very promising candidates for high-field applications owning to their ultrahigh upper critical field (Hc2) and very small anisotropy. For such applications, it is essential to develop multifilamentary superconducting wires with high transport critical current density (Jc). Compared with the tape-sharped multifilamentary wires with high aspect ratio,...
