F. Darmann et al., TRANSPORT AC LOSSES OF MULTIFILAMENT AG-SHEATHED BI-2223 TAPES WITH PERIODICALLY ARRANGED FILAMENTS IN THE Z(M).X-N CONFIGURATION, Superconductor science and technology (Print), 11(10), 1998, pp. 1049-1052
The powder-in-tube route for fabricating long lengths of multifilament
Ag-sheathed Bi-2223 tape can be used to manufacture tapes with a vari
ety of filamentary configurations. The design of the filament array wi
thin a tape will influence the electrical properties including the ac
loss which becomes a significant consideration when designing a closed
cooling system. The effect of periodically arranged filaments on the
transport ac losses of Bi-2223 tapes has been investigated and the res
ults compared with the Norris equations.
