c-Direction Finite Voltage in Bi-based/Ag Multifilament Tapes

摘要

A finite voltages along the c-direction of the Ag-sheathed Bi-2223 multifilament tapes have been measured, detected by voltage leads attached on the opposite broad faces of the tape. A theoretical analysis using magnetic flux creep and flow model and simplified electric network model is provided. The non-uniformity of the mass core density of the core and unsymmetric distribution of the cores over the transverse cross section result in the finite voltage.
