PROGRESS IN HIGH-TC MAGNET DEVELOPMENT IN OXFORD

Abstract We describe the development of magnet coils constructed using high-temperature superconducting tapes (2212 and 2223 BSCCO/Ag) from a variety of sources. The applications area for these coils are as high-field inserts for superconducting magnets, at or near 4.2 K, and as a source of ampere – turns (at 77 K) for iron circuits. The latter application is illustrated with a coil built for a successful demonstration of attraction levitation using direct control of the magnet current to maintain a fixed airgap.
