OSTI ID:6479498
Multifilamentary superconducting wire is used to produce high magnetic fields. One of the materials utilized is Nb/sub 3/Sn produced by ''bronze-type'' processes. To achieve peak properties the wire fabrication technique and the Nb/sub 3/Sn grain morphology and composition must be optimized. This work investigated the variation in critical current of an internal-tin-processed wire and a bronze-processed wire to determine the source of the superior properties in the internal tin wire. 74 refs., 4 tabs.
