Abstract

A superconducting device has a cryosystem to whose cryogenic medium a superconducting appliance and a superconducting switching path (which is electrically connected to it and can be activated thermally by means of a heater) of a superconducting switch are thermally coupled. A pipeline, to whose end the superconducting switching path is thermally coupled, is connected to a coolant area of at least one superconducting appliance. To ensure reliable heating of the switching path when the heater is activated, the pipeline has a cross-sectional constriction which impedes the heat exchange with the coolant area.
