Abstract:
An X-ray spectrometer comprising:an X-ray source; a curved crystal monochromator; a receiving slit; and a movement control mechanism in which an angle of incidence of a continuous X-ray beam from said X-ray source can be changed with respect to said monochromator so that a monochromatic X-ray beam of a different desired wavelength can be focused on and taken out from said receiving slit, provided that said X-ray source, said monochromator and said receiving slit must be positioned always on a Rowland circle, wherein said X-ray source and said curved crystal monochromator can be moved so that said angle of incidence changes, while said receiving slit remains stationary and a direction of an X-ray path from the center of said curved crystal monochromator to said receiving slit remains always constant during a change of said angle of incidence.
