Abstract:
1. An apparatus having a superconductor flux pump including a transformer having, on a secondary side thereof, at least one superconducting transformer coil, and at least one controllable switch, the pump being intended for feeding current into a superconducting coil of an electromagnet, wherein the at least one superconducting transformer coil on the secondary side of the transformer includes an HT c superconductor material, the at least one controllable switch has a switch gap being in the form of a strip, the at least one switch at least in part includes an HT c superconductor material in the form of a thin film which is applied to a buffer layer for texturing of the thin film, and wherein a controllable heater is arranged adjacent to and in thermally conductive contact with the switch gap.
