Large HTS Magnet Made by Improved DI-BSCCO Tapes

Performance of the high temperature superconductor (HTS) is rapidly progressing and applications of the HTS are also improving. Significant enhancements in J_c in Bi2223 long wires have been achieved. The wires produced by Sumitomo Electric Ind., are named DI-BSCCO (Dynamically Innovative bismuth-based HTS wire). A cryo-cooled high-field high-temperature superconducting (HTS) magnet, which is made of this DI-BSCCO and has a room-temperature bore of 200 mm in diameter, has been developed and tested up to 8.1 T. The design study of the magnet using the latest DI-BSCCO shows that the higher magnetic field can be produced with almost the same size of the magnet. This magnet can also be used in various industries such as bio-medicine, semiconductor and environmental industries.
