Abstract: A pulsed magnetic field is generated by a device having a magnet to be operated in pulse operation which contains at least one superconductive refrigerant-free winding that is disk-shaped or saddle-shaped. Also included is a refrigerating unit which has at least one cold head. A line system, having a refrigerant circulating in it according to a thermosiphon effect, thermally couples the winding to the cold head. The line system has a plurality of separate pipes lying next to one another. The pipes, open onto a common refrigerant distributor and closed at the other end, are thermally coupled to the surface of the disk-shaped or saddle-shaped winding.

Abstract: A switching path having superconducting material in a switching device may be cooled to a predetermined superconducting operating temperature. The switching device includes a mechanism for exceeding at least one of the critical values of the superconducting material in a controlled manner to change the switching path from the superconducting state to the normally conductive state. The switching device may have an operating temperature of below 40 K, and contain magnesium diboride as the superconducting material for its switching path.
