Description

A 9-tape (14mm width pre-cut, 4.9 mm post-cut) REBCO Roebel cable from Robinson Research Institute had MQE measured in a LHe bath at varying I/Ic in applied fields up to 12 Tesla. Quench was initiated using a 4.5 mm by 4.5 mm Nichrome film heater. Current sharing was monitored throughout the cable using transverse voltage taps and Tmax of the quench was measured with calibrated Type-E thermocouples. These measurements are part of a larger effort to understand stability in REBCO Roebel cables.
