X-ray optics assembly with switching system for three beam paths and associated x-ray diffractometer

摘要

PROBLEM TO BE SOLVED: To provide an X-ray optics assembly and an X-ray diffractometer, which may be used more universally for various measurement geometries in a simple manner.SOLUTION: An X-ray optics assembly 3 for an X-ray diffractometer 1 is provided, comprising a multilayer mirror 7, in particular a Goebel mirror, and a switching system 13 that allows for selecting a beam path 15 for an X-ray beam. The X-ray optics assembly includes a monochromator 9, in particular a channel-cut crystal 9a, and three beam paths are selectable for the X-ray beam using the switching system. A first beam path corresponding to a first position of the switching system extends past the multilayer mirror and past the monochromator. A second beam path corresponding to a second position of the switching system includes the multilayer mirror and extends past the monochromator. A third beam path corresponding to a third position of the switching system includes the multilayer mirror and the monochromator.SELECTED DRAWING: Figure 1
