Abstract:
1. An X-ray generating device comprising: an electron-beam generator that generates electron beams; a target assembly group including a plurality of target assemblies that are arranged in one line in a direction in which X-rays are output, each of the target assemblies including a target and a supporting member, the target generating X-rays from one of the electron beams generated by the electron-beam generator, and the supporting member being disposed adjacent to the target and supporting the target; and an electron-beam focusing unit that focuses the electron beams generated by the electron-beam generator onto the targets included the target assembly group, wherein the electron-beam focusing unit focuses the electron beams onto intersections of surfaces of the targets and a straight line that extends through the targets, and wherein X-rays that are generated along the straight line are output after passing through the target assemblies that are located on a side toward which the X-rays are output with respect to the position at which the X-rays are generated.
