Abstract

An X-ray tube includes a vacuum-filled housing and an anode contained in the vacuum-filled housing. The anode is operable to produce an X-ray beam based on electrons emitted from a cathode and attracted by a high voltage applied to the anode. The X-ray tube also includes a high-voltage power line introduced from an external side of the housing for supplying the anode with a high-voltage potential. The X-ray tube includes an electrical feed for electrically insulating the high-voltage power line from the housing. The electrical feed in the X-ray tube includes at least two insulating layers radially between the high-voltage power line and the housing. The at least two insulating layers are separated from one another by a metallic coating.
