摘要： The present invention relates to a high-voltage x-ray tube (R) with an inner vacuum chamber (11) in which lie, oriented opposite one another, a cathode (8) held at a negative high voltage during operating conditions and an anode (2) held at a positive high voltage during operating conditions, wherein the anode (2) is affixed to an anode isolation element (3a) such that the anode isolation element (3a) has a cylindrical form or a form tapering toward the anode (2) and comprises an opening (5a) to receive a high-voltage plug (12) and has a conductor structure (6/7) via which a coolant can be supplied to the anode (2). This coolant can be, in particular, an insulating oil or another electrically nonconductive liquid. The conductor structure (6/7) can, for example, be integrated completely into the interior of the anode isolation element (3a) but can also be integrated into the surface of the high-voltage plug (12). In another possible solution, the conductor structure (6/7) is integrated into an intermediate element (13) which lies between the anode isolation element (3a) and the high-voltage plug (12).
