The Conceptual Design of Hybrid High Temperature Superconducting Magnet

The anisotropy of electromagnetic performance of high temperature superconducting (HTS) tapes is significant. The performance of BSCCO and YBCO, both of which have been employed in industry already, is varied when they stand different orientations of magnetic field. In HTS magnet design, adopting optimization can directly affect the performance of magnet and the amount of the tapes employed in the magnet, namely affects the economy of magnets. Considering both the measurement results of magnetic field characteristics of the HTS tapes in the critical current and the technical requirement of the diminutive superconductor magnetic energy system(SMES) which is laboratory scale, this paper puts forward the technical scheme of making hybrid HTS magnet which employs both BSCCO and YBCO, then fulfills the optimization design of the hybrid HTS magnet by means of finite element analysis, which considers the performance of energy storing as constraint condition and the economical efficiency as destination. This paper verifies the superiority of employing two types of tape to make a HTS magnet.
