摘要： An x-ray tube includes a vacuum housing. A cathode and an anode are disposed in the vacuum housing and insulated by at least one insulation element. Upon application of a high voltage, the cathode emits electrons that strike the anode as an electron beam. A voltage arrester device with an insulation path has a field strength that is higher than a field strength at the insulation element. If a voltage flashover occurs, the voltage is discharged via the voltage arrester device.

摘要： 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.

摘要： A rotating envelope radiator has a radiator housing surrounded by an external housing to form an intervening space in which a coolant flows. To prevent the formation, at high rotational frequencies, of reverse flows of the coolant in the intervening space, a flow conductor structure is provided in the intervening space that counteracts the formation of tangential flow components in the coolant.
