Definitions

  • the invention relates to a rotating anode X-ray tube with a magnetically non-contact anode and means for dissipating the anode current.
  • the anode 2 has no mechanical contact with fixed parts during its rotation. So that the anode current can be transmitted without contact, the rotor 6 is designed as a hollow cylinder, which is on its inner man tel specifications is provided with ribs 9. The ribs 9 lie opposite ribs 10 on a fixed cylinder 11 which is connected to the anode connection 12.
  • the cylinder 11 carries two ball bearings 13, which are at a distance from the inner surface of the rotor 6 during the rotation of the anode 2, but support the rotor 2 when it is at a standstill.
