Abstract: The invention relates to an X-ray tube, an X-ray source and an X-ray facility. The X-ray tube may have a vacuum housing having at least one side surface, the vacuum housing comprises a cathode and an anode for generating X-rays. An acceleration path for emitted electrons is provided between the cathode and the anode via an applied high voltage. A first of the at least one side surface has a first electrically conductive housing section having a temperature dependent electrical conductivity so that an essentially linear potential curve is set along the acceleration path.

Abstract: A multitube X-ray emitter housing according to the invention includes a housing, a high-voltage supply and a cooling device with an electrically insulating cooling medium. The high-voltage supply has a plurality of high-voltage contacts connected in parallel on a single high-voltage supply lead. A first of at least one side surface of the housing has a first electrically conductive housing portion with a temperature-dependent electrical conductivity. The multitube X-ray emitter housing further includes: a control unit having an interface to receive a measured value representing the electrical conductivity of the first electrically conductive housing portion and to compare the measured value with a threshold value; and a switching device to switch off the high voltage based on the comparison.

Abstract: The embodiments relate to a liquid metal journal bearing including at least one first bearing part and at least one second bearing part. The bearing parts are non-positively connected to one another. Additionally, at least one sealing ring made of a ductile material is arranged between the first bearing part and the second bearing part. With a liquid metal journal bearing of this type, the escape of liquid metal is prevented, even under heavy loading. The liquid metal journal bearing is therefore suitable, for example, for installation in an X-ray generator.

Abstract: A rotating anode includes a focal track that has a microstructure on a surface of the focal track. The microstructure is produced using deep reactive ion etching.
