S.S. Cored 27-strand Nb3Sn Rutherford Cable was pressed onto a U-shaped holder and kept at magnet-relevant conditions throughout reaction, instrumentation, epoxy-impregnation, and measurement. Current was injected into a single strand of the cable under applied fields up to 15 Tesla and with varying I/Ic. Then, a graphite-paste heater pulse was used to initiate current sharing. ICR and current sharing was then measured using a hall-probe array and voltage taps. These measurements were performed using a small research magnet and are screening for cable and cable preparation protocol for larger scale measurements.
