BSCCO Based Superconductors for Magnet Applications
Industries and Universities are developing various types of BSCCO conductors for magnet and for power applications at intermediate (20–30 K) and at liquid nitrogen temperatures. The optimum application domains of different conductors are briefly addressed. The Bi-2212 conductor represents today the optimum cost versus performance solution for magnet applications in the intermediate temperature range. A review will be given on fabrication of the precursor powders, on conductor fabrication process, on heat treatments and finally on performances of the conductors. Alcatel pursues the development of multifilamentary tape-conductors by the rectangular deformation route. The ultimate test of performances of conductors is of course their use in systems. First applications are today opening in the magnet technology domain. Some aspects on coil fabrication by the complementary R&W and W&R fabrication process are given.
