Abstract: A toroidal x-ray tube housing (A) is composed of multiple sections which are clamped together and sealed by elastomeric gaskets (128). An annular anode (B) is mounted to the housing with coolant passages (12, 14) extending thereadjacent. A rotor (30) is rotated within the toroidal housing by a motor (60). At least one cathode assembly (C) is mounted to the rotor adjacent the anode. The rotor is supported by magnetic bearings (40) whose active coils are separated from the vacuum region by a magnetic window (48). Alternately, a series of vanes (136, 138) are provided to divide the vacuum chamber into a high vacuum region (132) adjacent the cathode and anode and a low vacuum region (134) adjacent the motor (60) and bearings (40, 150, 152) for rotatably supporting the rotor within the housing. An active vacuum pump, preferably a ion pump (112) and a getter (114) are hermetically sealed into the vacuum region for maintaining the vacuum.

Abstract: An x-ray tube includes an anode (A) and envelope (C) which are rotated (D) at a relatively high rate of speed. A cathode assembly (B) is supported in the envelope on a bearing (32). In order to hold the cathode assembly stationary, a magnetic susceptor (40) having periodic projections (44) is disposed with the projections closely adjacent an outer peripheral wall (20) of the envelope. A plurality of permanent magnets (52) are mounted on a stationary keeper (50), each magnet adjacent one of the susceptor projections. Preferably, the magnets have alternating polarity such that magnetic flux lines (54) flow between adjacent magnets through the magnetic susceptor.

Abstract: The invention relates to a fluorescence radiation source in which an anode which encloses a member is struck by electrons on its side which faces the member and in which the primary X-ray radiation generated in the anode generates fluorescence radiation in the member. The member is preferably arranged within an enclosing shield which keeps scattered electrons remote from the member.
