BI-2223 AG HTS COIL MAGNETIC-FIELD PROPERTIES FOR MAGNET AND BIAS WINDING/

Ag-clad (Bi,Pb)(2)Sr2Ca2Cu3O10+x high-T-c superconducting (HTS) multif ilament wire, is used to prepare a HTS coil. The magnetic field behavi our of the HTS coil is studied with respect to its critical current an d magnetic field properties. The anisotropic HTS wire has strong magne tic field dependent critical current, which causes critical current de gradation when used in the form of a coil. The HTS coil magnetic field is measured and its distribution is investigated. The experimental re sults and analysis provide basic information for the design of a magne t or bias winding with the Ag-clad (Bi,Pb)(2)Sr2Ca2Cu3O10+x HTS wire.
