MANUFACTURING METHOD OF PARABOLOID TYPE X-RAY REFRACTOR BY BE MATERIAL, AND MULTISTAGE LAMINATED MODULE

摘要

PROBLEM TO BE SOLVED: To provide an X-ray refractor capable of enduring long period high-voltage X-ray irradiation, and to provide a method wherein adjustment of an X-ray refractive index is easy in an X-ray condensing optical system.

SOLUTION: The manufacturing method of the paraboloid type concave shaped X-ray refractor from the Be material includes that surface grinding of both faces of the Be material is carried out to provide parallelism, an outline is circularly ground such that a ground face becomes perpendicular to the planes subjected to surface grinding, perforating is carried out to a circular center of the Be material from both faces wherein an obtained lens aperture part does not completely pass through the lens, grinding into a paraboloid type concave shape is carried out while leaving an optional bottom thickness, and mirror finish polishing is carried out. In the Be lens serial multistage type laminated module, a plurality of the Be paraboloid type X-ray refractors are serially arranged in a cylinder.
