摘要： In one example, an x-ray tube comprises an evacuated enclosure and a cathode disposed within the evacuated enclosure. An anode is also disposed within the evacuated enclosure opposite the cathode so as to receive electrons emitted by the cathode. A rotor sleeve is coupled to the anode, the rotor sleeve being responsive to applied electromagnetic fields such that a rotational motion is imparted to the anode. A magnetic assist bearing assembly rotatably supports the anode.

摘要： A device in accordance with the invention for the emission of X-rays, comprises a vacuum pump the sealed peripheral casing whereof contains a cathode for emitting a flux of electrons, a rotary anode mounted at the end of the shaft of the vacuum pump and a collection device for collecting an emitted electron beam. This considerably reduces the overall size of the X-ray source and, thanks to the very fast and stable rotation of the rotary anode attached to the rotor of the vacuum pump, a source of very great brightness is produced. The rotary anode may be moved axially to compensate the wear that it suffers through the impact of the incident electron beam coming from the cathode. According to the invention the device further comprises at least one cooling element fixed to the vacuum pump stator or to the sealed peripheral casing opposite one of the main radial faces of the rotary anode to absorb radiated heat energy emitted by the rotary anode in operation.

摘要： The invention relates to a rotating anode X-ray tube provided with a charge flow device, in which the anode current of the tube is established between an emitter coupled in rotation to the rotating anode, as well as a fixed collector. The latter is electrically connected to high voltage and the emitter is electrically connected to the rotating anode, having at least one part with a tapered end constituting an electron emissive zone. These electrons are trapped by the collector, so as to establish the anode current of the tube without any material contact between the emitter and the collector. The invention is applicable to radiology in general and more specifically to medical diagnosis.

摘要： Tubular electromagnetic components are mounted on the drive shaft of the ary anode of an X-ray tube and external magnet windings are provided both for maintaining the drive shaft in an axial position corresponding to a working position of the anode and for shifting the drive shaft to open a slip contact at one end thereof, thus providing a magnetic switch for the anode supply voltage. In addition, windings are provided through which a controlled current flows to provide a radially stabilized position for the shaft and thus constitute magnetic bearings that are free of friction. When one of the contacts of the magnetic switch is spring-mounted, the coil that does the switching can also be used to adjust the axial position of the anode so as to work with a different cathode.
