摘要

The main topics which were covered at the Workshop were the results of the Round-Robin Tests for critical currents I/sub c/ of Nb sub 3 Sn wires to identify a preferred method for measurements of I/sub c/; determination of relationship between microstructures and critical current density J/sub c/; and the present status of the oxide superconductors. In general, this workshop has again been very useful for exchange ideas and results among participants from two countries, and some main conclusions from the Workshop are the results from measurements of I/sub c/ of Nb sub 3 Sn wires are still inconsistent and further Round Robin tests are required to select a standard measuring technique; characterization of microstructures has advanced for some practical wires to the extent that a qualitative comparison between experiments and theories for flux pinning is becoming possible; and in spite of enormous excitements which were generated by discovery of the high T/sub c/ superconducting oxides, the values of J/sub c/ in this material have been low. The highlight of this section was the announcement of J/sub c/ approx. 1.1 /times/ 10 sup 4 A/cm sup 2 at 77 K at H = 0 in a short section of a wire of YBa sub 2 Cu sub 3 O sub 7 . This value is greater by /approximately/1 to 10 times that what has been previously reported. (ERA citation 14:014030)
