Definitions

  • the rotary anode X-ray tube shown in FIG. 1 has a metal piston 1 to which the cathode 3 is attached via a first insulator 2 and the rotary anode is attached via a second insulator 4.
  • the rotating anode has an anode disk 5, on the surface of which is opposite the cathode 3, when a high voltage is switched on, X-ray radiation is generated, which emerges through a radiation exit window 6 in the bulb 1, which preferably consists of beryllium.
  • the anode disk 5 is connected via a bearing to a carrier body 7 which is fastened to the second insulator 4. As can be seen in particular from FIG.
