Abstract

A series of one-meter long racetrack-shaped windings has been fabricated from BSCCO tape conductors obtained from four manufacturers. Two coils were built from each conductor type and tested in the “common coil” dipole configuration in liquid helium. The effect of the remnant magnetization currents determined by measuring the residual dipole sextupole fields after cycling the magnets to progressively higher currents. Two coil sets have been measured and the results are compared to those obtained from a Nb₃Sn ribbon magnet of the same geometry
