ABSTRACT:
The invention relates to a superconductive device containing a rotor that can be rotated about an axis of rotation and that comprises a superconductive winding in a winding support. Said winding support has a central cavity, into which two fixed thermal tubes project axially. One of said tubes forms a cooling finger that is closed at the end and contains a second coolant with a higher condensation temperature. The other tube supplies a first cooling with a lower condensation temperature to the central cavity and evacuates said coolant from the cavity. To condense the coolants, the tubes lead to a refrigeration unit, situated outside the rotor and equipped with a refrigeration head and a condenser device.
