Abstract: An x-ray tube with an anode which is located in a high vacuum chamber connectable to a vacuum pump and is passed through by cooling fluid. The anode which comprises a peripheral mantle surface and lateral surfaces which are approximately parallel to each other is disengageably connected to a rotatable hollow shaft for rotation therewith and has its peripheral mantle surface located within the region of the electron beams emitted by the cathode. The x-ray tube furthermore comprises a distributing member for distributing the cooling fluid, which distributing member is arranged in the interior of and coaxially with the rotatable anode. The peripheral mantle surface is formed by the central peripheral portion of a ring which has a U-shaped cross section and the legs of which are detachably connected to the lateral surfaces of the anode, O-rings being provided for sealing purposes between the legs of the ring and the lateral surfaces of the anode.

Abstract: An x-ray tube, in which a rotation-symmetric anode passed through by a cooling fluid and located in a first high vacuum chamber connectable to a vacuum pump is detachably connected to a rotatable hollow shaft having associated therewith cooling fluid supplying and discharging conduit means respectively and extending through the wall of and into the first high vacuum chamber while a second high vacuum chamber containing blocking fluid, e.g. oil, for purposes of sealing the area where the rotatable shaft penetrates the wall of and enters the first high vacuum chamber is provided between an outer chamber and a prevacuum chamber. More specifically, between the prevacuum chamber and the first high vacuum chamber there is provided the second high vacuum chamber which is separated from the prevacuum chamber by first sealing means and from the first high vacuum chamber by at least a wall surface portion of the rotatable anode and by the second sealing means having a wall close and parallel to the rotatable anode. The second high vacuum chamber extends over the first sealing means while that wall of the second high vacuum chamber means which is located opposite the first sealing means simultaneously forms a wall of a cooling passage passed through by a cooling fluid.
