“…Short tapes were melt processed in pure oxygen using a three-zone tube furnace. The detailed thermal treatment schedule has been described elsewhere [9]. Montages, showing a representative segment of the tapes, were assembled and used to measure the thickness of the Bi-2212 filament.…”

“…In contrast, the contribution from the superconductor core to the overall current-carrying capabilities of the PIT tapes is insignificant. A recent study showed that smooth Ag-oxide interfaces in the Bi-2212 tapes, which lead to a homogeneous and highly aligned microstructure, are essential for obtaining desirable J c values [8,9]. Therefore, it appears that highperformance superconducting tapes need to increase the effective current-carrying cross-sectional areas and retain good grain alignment along the interfaces after the partial melt process.…”

“…Conceivably, the new configuration can take advantage of the existing knowledge of monocore tape and meet the essential geometrical and dimensional requirements set forth for multifilamentary tapes. Most of the processing variables were chosen based on the previous studies on monocore wires and tapes [9,10]. Also, the manufacturing process was designed so that long conductors can be readily produced.…”
