Abstract: It is described an X-ray tube (100) comprising a rotating anode (130), which is provided with a pull electrode (140). The pull electrode (140) interacts with a fixed electron source (110) in order to generate a modulated electron beam (120a, 120b). The beam modulation may be an intensity variation and/or a spatial deflection. The pull electrode (140) is mounted in a fixed position with respect to the anode (130) and rotates together therewith. The pull electrode (140) may have a hole (141) for passing the electron beam (120a). When being in front of the electron source (110), the pull electrode (140) causes a high electric field (142a) such that a strong electron beam (120a) is generated. When being not in front of the electron source (110) only a low current or a zero current electron beam (120b) is generated. However, the pull electrode (740) may also cause a radial beam deflection such that depending on the angular position of the anode (730) the position of a focal spot (721a, 721b) of the electron beam (720) is varied.

Abstract: An X-ray tube device (100) according to the present invention includes a cathode (1) generating an electron beam, an anode (2) generating an X-ray by collision of the electron beam from the cathode, an envelope (3) internally housing the cathode and the anode, a magnetic field generator (4) including a magnetic pole (4b) arranged to be opposed to the envelope, generating a magnetic field for focusing and deflecting the electron beam from the cathode to the anode, and an electric field relaxing electrode (5) arranged between the magnetic pole and the envelope, having an outer surface having a rounded shape. Thus, the magnetic field generator can be placed closer to the envelope while a tip end of the magnetic field generator is suppressed from being a discharge start point, and hence the effect of being capable of downsizing the X-ray tube device is achieved.

Abstract: In an envelope rotation type X-ray tube apparatus 1, a cathode 5 releases electrons, and the electrons released from the cathode 5 are deflected by deflection coils 6. A target 7 generates X-rays by being bombarded with the electrons deflected by the deflection coils 6. Here, a shield ring 11, while allowing passage through a ring interior of those of the electrons deflected by the deflection coils 6 that head for an area F of the target 7 set beforehand, blocks electrons heading outward of the area F. Consequently, the electrons are inhibited from bombarding on areas of the target 7 outward of the area F and an envelope 2. This can prevent damage to the envelope 2.

Abstract: Conventionally, the magnetic field generator 4 was arranged perpendicularly to the axis O of the electron beam B. The magnetic field generator 4 of this invention is arranged so as to be inclined relative to the axis V perpendicular to the axis O of the electron beam B. Specifically, the magnetic field generator 4 is arranged so as to be inclined relative to the axis V perpendicular to the axis O of the electron beam B within the range in the cathode 2 side from the focused and deflected electron beam B. Inclination up to the anode 5 side opposite to the cathode 2 side will lead to a possibility of increasing the reduced X-ray source diameter. Thus, arranging the magnetic field generator 4 so as to be inclined within the range in the cathode side from the electron beam B may reduce the X-ray source diameter.
