ABSTRACT:
Parallel X-ray beams with two kinds of wavelength are made with the use of a single parabolic multilayer mirror. A single parabola prepared for a CuKa X-ray is used for making parallel X-ray beams of both the CuKa X-ray and the CoKa X-ray. The CuKa ray emitted from a first X-ray focal spot located at the focus of the parabola is reflected at a reflecting surface composed of the parabola to become a parallel beam going out. When a second X-ray focal spot is arranged at the position apart from the first X-ray focal spot by a predetermined distance, the CoKa X-ray emitted from the second X-ray focal spot is reflected at the same reflecting surface to become a parallel beam going out.
