X-RAY TUBE

摘要

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.
