Pyrolytic graphite monochromator with curved surface and method for manufacturing the same

摘要

A pyrolytic graphite monochromator having a curved surface has at least one diffractive surface of graphite crystals in order to diffract and monochromize X-rays generated from an X-ray source and concentrate the same at a predetermined point, and the diffractive surface is a curved surface . In the method for producing a pyrolytic graphite monochromator having a curved surface of the present invention, a step of forming a carbonaceous film by heating one or more polymer films at a predetermined temperature within a range of 400 to 3500C, The carbonaceous film is heat-pressed on a predetermined curved surface of the graphite die at a predetermined temperature within a range of 400 to 3500C while applying a predetermined pressure to the at least one superposed and formed carbonaceous film placed on a predetermined curved surface, And forming the monochromator of the graphite crystal having a curved surface corresponding to the predetermined curved surface.
