ABSTRACT:
A rotating anode x-ray tube has a rotating anode contained in a vacuum-sealed housing with a compartment for a cathode projecting from a cover of the housing opposite the rotating anode. To improve the durability, a transition part connecting the compartment with the cover has high-temperature stability that is greater than that of the cover or of the compartment.
