摘要： 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.

摘要： 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.
