Abstract
The cylindrical peripheral wall (5) of a rotating hollow body mounted on a haft (1) driven by an electric motor within the stem casing of an X-ray tube is cooled with water supplied and removed respectively through co-axial ducts in the drive shaft, distributed by radial ducts in one end face of the rotary body to a ring duct and gathered from a ring duct at the other end face through another set of radial ducts leading back to the shaft. Between the two ring ducts the cooling medium flows through helical cooling ducts running parallel to each other and at an angle of about 15.degree. to the edge boundaries of the cylindrical operating surface. These ducts are formed on the outside by the anode peripheral wall material itself and on the inside by a stainless steel insert. The anode is degassed when its structure is soldered or brazed together in high vacuum at 1000.degree. C.
