摘要

We report recent progress in 2G-HTS wire technology at SuperPower Inc. The throughputs of 4mm-wide tape have reached 750m/h for sputtering Al_2O_3+Y_2O_3 base layer, 360m/h for IB AD MgO template, 345m/h for sputtering Homo-epi MgO+LMO buffer, 180m/h for MOCVD REBCO. Critical current (Ic) of 813A/cm-width at 77K and self-field has been achieved on 1 meter length of 12mm-wide tape. In-field performance has been significantly improved through composition modification, doping and MOCVD condition optimization. Ic of 185.6A/cm-width at 77K and 1Tesla has been obtained. For Ic on long lengths, 314A/cm-width on 202m, 221 A/cm-width on 610m and 170A/cm-width on 935m have been achieved. A coil of 19.1mm diameter that we made with our 2G wires generated 26.8T magnetic field. A 30m-long cable made with nearly 10,000 meters of SuperPower 2G wires showed excellent overall performance and has been installed and energized in the power grid.
