Abstract

A conductor element consisting of laminated stack of high temperature superconductor (HTS) powder-in-tube (PIT) tapes is suitable for incorporation into current leads. The details of an application of such conductor elements to a current lead for a SMES system are presented. The fabrication of the laminated-conductor elements made with BSCCO 2223 PIT tapes is described. The critical current measurement method and results for two such conductor elements are presented. Performance was evaluated with variable temperatures and with variable applied fields.
