SUPERCONDUCTING DEVICE WITH A COLD HEAD, WHICH IS THERMALLY COUPLED TO AROTATING SUPERCONDUCTIVE WINDING, OF A REFRIGERATION UNIT

摘要

The superconducting device (2) comprises a rotor (5) which is rotatable about an axis of rotation (A) and is provided with a superconductive winding (10) in a heat conducting winding carrier (9). The winding carrier (9) has a central cooling agent cavity (12) with a lateral cavity (13) leading out of the winding carrier (4) connected thereto. A cold head (16) associated with a cooling unit (16) is connected to a condenser unit (18) which condenses the cooling agent (k, k'). A fixed heat tube (20) guiding the cooling agent (k, k') is coupled to the condenser unit (18), protruding axially into the co- rotating lateral cavity (13) and is sealed in relation thereto.
