Summary

SUPERCONDUCTING MATERIALS OF NBTI, NBTIZR, TINBZRTA, NB3SN, AND V3GA ARE MANUFACTURED BY EIGHT JAPANESE COMPANIES. BECAUSE THERE ARE NO STANDARD METHODS TO MEASURE THE VARIOUS SUPERCONDUCTING PARAMETERS, EACH COMPANY DETERMINES THEIR OWN MEASURING TECHNI-QUES. IN THIS REPORT, THE METHODS EACH JAPANESE MANUFACTURER USES TO MEASURE THE SUPERCONDUCTING PARAMETERS OF CRITICAL CURRENT, STABILITY, TRANSIENT OR AC LOSSES, PHYSICAL AND MECHANICAL PROPERTIES, CRITICAL TEMPERATURE, CRITICAL FIELD, AND MATERIAL COMPOSITION OF PRACTICAL SUPERCONDUCTORS ARE DISCUSSED. THE REPORT SHOWS THAT THERE IS A LARGE VARIATION BETWEEN THE MEASUREMENT METHODS OF THE MANUFACTURERS AND IN THE DEFINITIONS FOR THE VARIOUS PARAMETERS.
