Claim Text:
1. A cooling device for a superconductor, comprising: a cooling circuit for a coolant, the coolant being liquefied in a cold head with a condenser being conducted to the superconductor to be cooled, and being returned to the condenser in a gaseous form, wherein a pressure generated by a component of the coolant, evaporated by way of a heat source, is used to convey the coolant from the condenser to the superconductor, and wherein the heat source is a heating device, operable cyclically, wherein a ratio of an operating phase of the heating device to a non-operating phase of the heating device is greater than 50%, and/or heating power during the operating phase is less than double the cold head cooling power; a reservoir for liquid coolant, connected by a first line segment to the condenser and by a second line segment to a part supporting the superconductor to be cooled, the heat source being coupled to the reservoir; and a valve, provided upstream of the reservoir on the condenser side, wherein the valve utilizes gravitation forces and is disposed in a rising part of a siphon adjacent to the reservoir.
