Abstract :
A technical working party in the area of superconducting and cryogenic structural materials has recently carried out the first worldwide intercomparison of critical-current, Ic, measurement on multifilamentary Nb3Sn wires. Three sample wires were supplied from each of the European Community countries, Japan, and the United States. There were few restrictions for the I c measurement at participant labs. The standard deviations of the Ic values reported from these labs varied among test samples, and were 6-21% of averaged Ic s at 12 T
