Abstract
In an exemplary embodiment, the rotary anode is mounted by magnetic bearings and is provided with an auxiliary device for conducting the anode current to the external power supply. The auxiliary device comprises at least one auxiliary cathode which rotates with the anode and an auxiliary anode which is arranged concentrically to the anode rotary axis on a stationary part. The heating of the auxiliary cathodes can proceed via generator windings which rotate with the rotary anode and associated stationary exciting windings arranged about the x-ray tube. It is also possible to provide for this purpose a rotating transformer whose primary windings externally annularly surrounds the x-ray tube and whose secondary winding is arranged on a rotating anode part.
