VAMAS intercomparison of critical current measurements on Nb3Sn superconductors: A summary report

A probe for investigating the effects of temperature, strain, and magnetic field on transport critical currents in superconducting wires and tapes

“…We conclude that the thermal expansion of CuBe is well matched to NbTi and Nb 3 Sn composites and better than either stainless steel or brass. 30 To ensure that the current flows through the superconductor, the electrical resistivity of the spring should be relatively high. This is particularly important for samples that have small cross sections compared to the section of the spring.…”

Final Technical Report

“…The history of interlaboratory comparisons of measurements on superconductors tells us that careful measurement methods are needed to obtain consistent results [1][2][3][4][5][6][7][8][9][10]. Inconsistent results can lead to many problems including: a mistrust of the results of others, unfair advantages in commerce, and erroneous feedback in the optimization of conductor performance.…”

“…Industrial development of conductors exhibiting such unprecedented properties as those listed in Tables II and III Inspired by the VAMAS program [32] and the successful development of standardized procedures for measuring the critical current of ITER conductors [33], the WGCC has initiated a cross-calibration program between the various test facilities in order to:…”
