Abstract:
1. An X-ray generator, comprising: an anticathode in which a plurality of anticathode parts radiating X-rays by collision of thermoelectrons are disposed side by side; a cathode to release the thermoelectrons towards one of the anticathode parts on said anticathode unit; and a cathode moving mechanism to switch the anticathode parts, against which the thermoelectrons collide from a cathode, by moving the cathode in an aligning direction of the anticathode parts on the anticathode unit, wherein an optical element that emits incident X-rays as diffracted X-rays is arranged in a taking-out route of the X-rays radiated from the anticathode parts, and by adjusting an angle of the optical element, an adjustment mechanism is also provided to align emitting directions of the diffracted X-rays with respect to the incident X-rays emitted from each anticathode, to one direction, when the anticathode parts, against which the thermoelectrons from the cathode collide, are switched by moving the cathode.
