In a high-voltage X-ray tube, which a cathode, which is held at negative high voltage during operating conditions, and an anode, which is held at positive high voltage during operating conditions, are disposed opposite each other in a vacuumized inner space, the anode being attached to an anode insulation element in such a way that the anode insulation element has a cylindrical shape or a shape tapering toward the anode and includes an opening to receive a high-voltage plug, and a pipe structure is provided by means of which a coolant is able to be supplied to the anode. This coolant can be in particular insulating oil or another electrically non-conducting liquid. The pipe structure can, for example, be integrated completely into the interior of the anode insulation element, but can also be integrated into the surface of the high-voltage plug. A solution is also possible in which the pipe structure is integrated into an intermediate element, which is situated between the anode insulation element and the high-voltage plug.

X-ray tube with an anode insulation element for liquid cooling and a receptacle for a high-voltage plug

X-ray tube () for high dose rates, a corresponding method for generating high dose rates with X-ray tubes () as well as a method for producing corresponding X-ray devices (), in which an anode () and a cathode () are disposed opposite each other in a vacuumized internal chamber (), electrons e&#x2212; being accelerated to the anode () by means of impressible high voltage. The anode () is made of a layer or coating of a metal having a high atomic number, for conversion of the electrons (e) into X-ray radiation (&#x3b3;) with cooling. The cathode () comprises a substrate substantially transparent for X-ray radiation (&#x3b3;). In particular, the likewise substantially transparent for X-ray radiation (&#x3b3;). In particular, the cathode () can close off the vacummized internal chamber () toward the outside.
