Abstract

Flux distributions of multifilamentary Bi-2223 tapes with a varying number of filaments (14 to 55 filaments) are investigated by magneto-optic (MO) imaging at various temperatures (10 ≤ T ≤ 77 K) and in different field orientations (field applied perpendicular to the tape surface and perpendicular to a cross section of the tape). This enables to study differences between the individual filaments in a direct way. From an analysis of the field distributions of the cross sections we obtain important informations concerning the filament quality as a function of position, and the filament coupling.
