Реферат: The design of a synchrotron radiation X-ray fluorescence analysis (SRXFA) station installed at the VEPP-3 is described, and the basic parameters of the station are given. A double-crystal monochromator offers the possibility to work in the 4-40 keV range of excitation energies. X-ray optic elements for primary and secondary monochromatization and radiation focusing are made, by an original technology, from formed pyrolithic graphite with a curvature radiusa of 240-5 mm. Using a scanning system, we have obtained the element maps of geological and biological objects at concentrations up to 1 ppm and spatial resolution up to 30 μm. Using the dispersion filters makes it possible to perform analysis at an element content less than 10 ppb. Our analysis is exemplified by the case with complete external reflection, and some other experimental results are given as well.
