ABSTRACT:
A turbomolecular pump coaxial with the drive shaftof a rotary anode in an ray tube is provided between the radial seal of the drive shaft and the high vacuum space surrounding the rotary anode. A pot-shaped shell mounted on the drive shaft where the latter passes through its bottom carries the rotor vanes, while the stator vanes are fixed on the tube casing. In order that the anode may be driven with the built-in electric motor located within the tube casing between the drive shaft bearings, at the high speed desirable for the turbomolecular pump, the rotary anode is cooled by water flowing through a set of closely adjacent helical ducts just inside of the working anode surface, running at a pitch of 10.degree. to 15.degree., fed with cooling liquid from radial ducts and a ring duct along one end face of a rotary anode and drained by another ring duct and another set of radial ducts along the other face of the rotary anode.
