ABSTRACT:
Apparatus to maintain a thermally insulating vacuum in a rotor of a turbogenerator with a superconductive excitation winding is disclosed. A sorption pump is mounted within the rotor in close proximity to the superconductive winding. The cooling system for the superconductive winding also serves to cool the sorption pump. The pump includes an arrangement for protecting the adsorbent material from radiation. The radiation protection is in the form of offset openings in the pump housing to form a labyrinth. Chambers are provided in the pump for the adsorbent material. These chambers are separated by walls or screens to retain the adsorption material in place as the rotor turns. The sorption pump is provided with a heating device in order to regenerate the adsorbent material.
