| Abstract | ABSTRACT: The magneto-optical imaging technique is used to measure magnetic flux distributions on the surface of a multifilamentary Ag-sheathed Bi-2223 tape at 20 K. The results are analysed quantitatively on the filamentary scale using a critical-state model approach. The flux distributions on a global scale are found to be similar to the Bean model predictions for a monocore tape. In addition, a fine structure associated with the arrangement of individual filaments is observed. We show that the detailed flux profiles in a number of different magnetic and current-carrying states can be well described by the thin-strip Bean model applied to the individual filaments. |
