Abstract

Transversal and longitudinal homogeneity of Bi-2223/Ag tapes made by a tape-in-rectangular tube process with high filament aspect ratio was studied. Spatially resolved transport measurements (“magnetic knife”), Hall probe measurements and local V–I measurements were used to obtain the Ic distribution across and/or along the tape sample. The Ic distribution in the width of the filaments shows a minimum in the filaments centre and a maximum is measured near the filament edges. A periodical variation of longitudinal Ic values is observed by local V–I and by Hall probe measurements. Transversal and longitudinal filaments cross-sections were obtained and compared to transport critical currents.
