ReBCO-CORC wires, long dreamed about practical high current density thin conductors, are now reality and feature diameters in the 2 to 4 mm range. They are multi-purpose, but at CERN specifically developed for application in high-field magnets. CERN is interested to further aid the development of such conductors for possible implementation in the next generation of accelerator magnets and...
Advanced Conductor Technologies has been developing high-temperature superconducting Conductor on Round Core (CORC®) cables and wires wound from ReBa2Cu3O7-x coated conductors for use in high-field magnets. Initial development is aimed at CORC® cable performance goals of operating currents exceeding 5-10 kA and engineering current...
A pancake coil was prepared with a length of 15-strand ReBCO 2G Roebel cable and studied in detail at different operating temperatures between 4.2K and 77K, cooled with either liquid cryogens or flowing liquid helium gas. The coil was impregnated with epoxy and the transient cooling was predominantly by conduction from current contacts. Critical current measurements were carried out with a...
The National High Magnetic Field Laboratory (NHMFL) is in the fortunate situation to put substantial effort into advancing all three high field magnet relevant types of high temperature superconductor (HTS) technologies, REBCO, Bi-2223, and Bi-2212, as a part of its commitment to develop all-superconducting high field magnets. Here we are presenting our work on Bi-2212 coil technology, which...
Two subscale coils of Bi-2212 wire have been made and tested in a DOE STTR collaboration between Cryomagnetics and the Applied Superconductivity Center at Florida State University. The coils are used to test the feasibility of using small-diameter wire in a solenoid configuration where single strand wire performance is crucial. If successful, the implementation of small-diameter wire into high...
