Abstract :
We measure transport ac losses in an 8/2 (eight 2-mm-wide strands) YBCO Roebel cable at 77 and 65 K without dc parallel magnetic field, and at 77 K under dc parallel magnetic fields of 0-1.5 T. The transport ac loss in the Roebel cable scales with temperature and dc parallel magnetic field as the square of the cable´s critical current.
