Abstract

An x-ray radiator has a rotary-bulb tube, whose vacuum enclosure rotates inside a radiator housing, which is filled with a liquid cooling medium, and a cooling medium conducting body is arranged between the vacuum enclosure and the radiator housing, at a distance from both of these. The cooling medium conducting body produces a flow of the cooling medium along the vacuum enclosure in the inner gap and a return flow of the cooling medium along the radiator housing in the outer gap, promoted by the rotation of the rotary-bulb tube.
