Based on a successful 1 T Class PIT insert coil, the authors are now pursuing a 3 T Class insert coil. This paper describes the design and the latest conductor and coil test results, as well as supporting experiments. The final product is envisioned to contain 3 concentric sections, requiring over one kilometer of conductor. This will be tested in a 20 T(More)
The critical current of the tapes prepared using continuous processing is significantly enhanced and processing time reduced, compared with that of traditional processing. The effect of conductor pulling speed on the microstructure, phase purity and therefore critical current of the tape is investigated using ESEM, XRD and DC transport measurements.
For the Ag-sheathed Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub 8/ tapes, the high Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub 8/ phase purity with an appropriate oxygen concentration and excellent grain alignment are responsible for high critical currents. Many fabrication parameters influence the Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub 8/ phase content and microstructure of the(More)
