Pulsed magnetic field losses of two 15000 A test superconductors designed for the swiss fusion research LCT coil

Pulsed magnetic field losses have been investigated on two different NbTi superconductors designed for direct cooling with supercritical He and for I
tr
= 15000 A. The loss measurements were performed with perpendicular and parallel pulsed field components. The influence of the dc field component on the pulsed field hysteresis losses was measured up to 7 Tesla.
