Abstract

A super conductor is disclosed, in particular a high temperature super conductor of a synchronous machine, including a cooling circuit for a coolant. The liquefied coolant in the cold head provided with a condenser is guided to the super conductor which is to be cooled, in particular in the rotor of the synchronous machine and is returned to the condenser in a gaseous form. In order to guide the coolant from the condenser to the super conductor, pressure generated by a component of the coolant evaporated by a heat source is used.
