Abstract

A single-pole x-ray emitter includes an emitter housing, in which an x-ray tube with a vacuum housing and a drive motor are arranged. A cathode that generates an electron beam, and a rotating anode that is struck by the electron beam along a focal path are arranged in the vacuum housing. The vacuum housing includes a drive-side housing wall and an anode-side housing wall, and the rotating anode is held in a torsionally rigid manner on an anode tube that is rotatably mounted on a stationary part of a rotor shaft that is coupled to the drive motor. The stationary part of the rotor shaft is joined to the anode-side housing wall of the vacuum housing via a ring-shaped fixing. The anode tube incorporates a temperature compensation element. The focal path is arranged on a side of the rotating anode that faces away from the anode-side housing wall.
