    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: An electron source emits electrons as a function of input signals. The electron source comprises a substrate (1), a matrix of wires having m row wires and n column wires laid on the substrate with an insulator layer interposed therebetween, and a plurality of surface-conduction electron-emitting devices each having a pair of electrodes (5,6) and a thin film (4) including an electron emitting region (3) and arranged between the electrodes. The electron-emitting devices are so arranged as to form a matrix with the electrodes connected to the respective row and column wires. Each pixel unit is irradiated by at least two electron beams emitted from the respective electron emitting regions which are juxtaposed with interleaving the higher potential device electrode therebetween and a gap interval W in the juxtaposing direction of which satisfies equation (1) below: K2 x 2H(Vf/Va) ≥ W/2 ≥ K3 x 2H(Vf/Va) where K2 = 1.25 +/- 5.05, K3 = 0.35 +/- 0.05, H is the distance between the surface-conduction electron-emitting devices and the image-forming member, Vf is the voltage applied to the surface-conduction electron-emitting device and Va is the voltage applied to the image-forming member.
