Abstract: An X-ray tube has a cathode housing having a radiation exit window, a cooled anode, a hot cathode, an insulation body, a supply line for coolant to the anode and a discharge line for coolant from the anode. The supply and discharge lines have a plurality of turns in the insulation body. The potted body has an inner and outer mold. The anode, the cathode housing and the potted body are fastened on the ceramic body. At least one plastic directing body aligns the hoses separated from the outer and inner mold. The potting space is filled with a plastic potting compound in a cured state so that the intermediate spaces between the turns on the one hand and the outer mold and the inner mold on the other hand are occupied by the plastic of the at least one directing body and/or the plastic of the potting compound.
