ABSTRACT:
In exemplary embodiments, the anode is driven by an induction motor, between the stator and rotor of which the wall of the vacuum envelope of the tube is disposed. To reduce the overall length and the lever actions of the weight of the anode which act on the bearing which are disadvantageous in this construction, the disclosure provides an annular anode which is disposed in the same plane with the drive rotor. The rotor and stator can here be surrounded by the ring of the anode or they can be secured externally about the latter. X-ray tubes in accordance with the disclosure are particularly suited for use for the purpose of medical x-ray examination.
