摘要： An electron gun includes a cathode portion which emits electrons, an anode portion which accelerates the emission electrons, a bias portion which is arranged between the cathode portion and the anode portion and controls trajectories of the emission electrons, a shielding portion which is arranged below the anode portion and shields some of the emission electrons, and a cooling portion which cools the shielding portion. The bias portion controls the trajectories of the electrons so as to form a crossover between the bias portion and the anode portion, and prevents the electrons from emitting on the anode portion.

摘要： A compact apparatus can form multi-X-ray beams with good controllability. Electron beams (e) emitted from electron emission elements (15) of a multi-electron beam generating unit (12) receive the lens effect of a lens electrode (19). The resultant electron beams are accelerated to the final potential level by portions of a transmission-type target portion (13) of an anode electrode (20). The multi-X-ray beams (x) generated by the transmission-type target portion (13) pass through an X-ray shielding plate (23) and X-ray extraction portions (24) in a vacuum chamber and are extracted from the X-ray extraction windows (27) of a wall portion (25) into the atmosphere.

摘要： An X-ray imaging apparatus includes a multi X-ray generating unit in which multiple X-ray foci are disposed in two-dimensional form at a predetermined pitch in a first direction, and a slit unit having multiple slit members each disposed opposite to its respective X-ray focus. Each slit member has multiple slits arranged in the first direction, and each of the slits forms a slice-formed X-ray beam whose lengthwise direction is a second direction that is different from the first direction. The two-dimensional detection unit detects the X-ray intensity of the formed X-ray beams at the detection surface. The X-ray imaging apparatus executes X-ray imaging at multiple positions while moving the multi X-ray generating unit and the slit unit in the first direction by the amount of the predetermined pitch, while keeping the relative positional relationship therebetween, and reconstructs an X-ray image based on the obtained X-ray intensity.
