Résumé

The paper describes a high-temperature superconducting (HTS) current lead, in which, over a short length at the warm end (e.g. 80 K), the lead, comprised of paralleled BSCCO-2223/Ag-Au tapes, is operated in the current-sharing mode. Because the leads rely on cooling by the effluent helium vapor, they are applicable only to devices such as superconducting magnets that operate in a bath of liquid helium. The current-sharing mode operation results in a significant saving of the superconducting materials (BSCCO, Ag, and Au) needed to construct the leads as compared with a "fully-superconducting" HTS lead of the same configuration that is rated for the same transport current and operates over the same temperature range.
