Outline of Final Research Achievements |
The multifilamentization for low AC loss and the cabling assembly for enhancing current capacity, which have been adopted to conventional low-Tc superconducting wires, are inapplicable to REBCO superconducting wires with a tape shape. In this study, by proposing a tremendous concept, the reduction of magnetization and AC loss of REBCO superconducting tapes and the enhancement of current capacity were realized. The evaluation and analysis of the electromagnetic properties of REBCO superconducting tapes and parallel conductors brought us the desirable basic-structure of REBCO tapes, conductors and windings, which are useful for any applications at the wide range of frequency, i.e., DC to a commercial frequency.
