Abstract: An x-ray radiator has a housing containing a fluid coolant wherein a rotating bulb x-ray tube is rotatably seated, the rotating bulb x-ray tube having an evacuated vacuum housing containing a cathode and an anode, with the anode forming a wall of the vacuum housing and having an exterior charged by the coolant. The anode has a profiling at its exterior that enlarges the surface area contact between the exterior of the anode and the coolant. The profiling can be in the form of at least one channel proceeding from as a spiral from a central region of the anode toward its periphery.
