    Abstract: The present invention provides an X-ray generating tube including a transmission target having a minute focal spot. The X-ray generating tube includes a transmission target having a first surface and a second surface opposite to the first surface, the first surface being irradiated with an electron beam, and the target radiating X-rays from the second surface; an electron emitting source emitting the electron beam in such a manner that the electron beam obliquely enters the first surface; and a tubular forward shield member located at the second surface side of the target to define an extraction angle of an extracted X-ray beam. The forward shield member is disposed such that a central axis of the electron beam and a central axis of the X-ray beam whose extraction angle is defined are located at the same side with respect to a virtual normal plane perpendicular to the first surface and a projection central axis that is a projection of the central axis of the electron beam to the first surface.

    Abstract: In an X-ray generation apparatus (10) of transmission type including an electron emission source (6), and a target (1) generating an X-ray (14) with collision of electrons emitted from the electron emission source against the target, the X-ray generation apparatus further includes a secondary X-ray generation portion (5) generating an X- ray with collision of electrons reflected by the target against the secondary X-ray generation portion, and the secondary X-ray generation portion and the target are arranged such that the X-ray (14) generated with the direct collision of the electrons against the target and the X-ray (15) generated with the collision of the electrons reflected by the target against the secondary X-ray generation portion are both radiated to an outside. X-ray generation efficiency is increased by effectively utilizing the electrons reflected by the target.

    Abstract: In a target structure (100) according to the present invention, a target (102) is provided on a central area of an insulating substrate (101), and a first conductive member (103a) for supplying a voltage to the target is provided on a peripheral area of the insulating substrate which is exclusive of an area overlapping the target and is not covered by the target, so that the first conductive member is in contact with and electrically connected to the peripheral portion of the target. Consequently, it is possible to easily form a voltage supply line to the target without preventing diffusion of a heat generated in the target to the substrate and while suppressing emission of an unnecessary X- ray.

    Abstract: A flat panel image-forming apparatus comprises a rear plate (1) including electron emitting devices (2) on its surface and a face plate (4) including a fluorescent film (5). The face plate and rear plate are assembled and sealed with an outer frame. Spacers are provided for mechanical rigidity. The assembled structure is evacuated by means of vent tubes (9). To facilitate evacuation in a short time, the spacers are arranged in rows and columns and are staggered in position relative to each other, in alternate rows and columns, in a zigzag pattern, and do not lie on straight lines connecting any two of the vent tubes.
