ABSTRACT:
To solve a difference in an emitting directions by switching the types of X-rays. An X-ray generator comprises: an anticathode unit3in which a plurality of anticathode parts2(2A and2B) that emit X-rays by collision of thermoelectrons are disposed side by side; a cathode4for releasing the thermoelectrons toward the anticathode parts2A and2B on the anticathode unit3; and a cathode moving mechanism that switches the anticathode parts, against which the thermoelectrons from the cathode4collide by moving the cathode4along the diction of aligning anticathode parts2A and2B. In such an X-ray generator, an optical element6is arranged, which emits incident X-rays R1and R2, in a taking-out route of the X-rays emitted from the anticathode parts2, as diffracted X-rays R11and R12, and also an adjustment mechanism7that aligns emitting directions of the diffracted X-rays with respect to the incident X-rays emitted from each anticathode part, to one direction, when the anticathode parts, against which the thermoelectrons from the cathode collide, are switched by moving the cathode.
