High field Ic characterizations of commercial HTS conductors

High field Ic performance of commercial high Tc superconductors, in view of applications such as an insert magnet for high field generation beyond 20 T, needs to be directly measured as no comprehensive relationships exist with the readily accessible 77 K self-field data. We have constructed and tested the measurement probes for high field beyond 20 T using the facility available at LNCMI-Grenoble, and report here the results of the measurements performed on recent commercial conductors relevant to high field applications.
