Abstract (en)

[origin: EP0151878A1] Disclosed is a rotating-anode X-ray tube which comprises a housing (10), a cathode (22) and a rotating anode (26) arranged in one end side of the housing, a rotating cylinder (40) set in the other end side of the housing (10) and adapted to be rotated by an electric motor (52), the rotating cylinder (40) supporting the rotating anode (26), a magnetic bearing (60) disposed in the other end side of the housing (10) and supporting the rotating cylinder (40) uncontacted in the radial and axial directions thereof, and a shielding wall (34) for dividing the inside space of the housing (10) into a first chamber containing the cathode (22) and the rotating anode (26), and a second chamber containing the magnetic bearing (60), whereby the first chamber is thermally and electromagnetically shielded from the second chamber.
