A grid-type semitransparent X-ray monochromator

摘要

A grid-type semitransparent X-ray monochromator is described. It can be used for splitting polychromatic beams, mixing beams of different spectral compositions, and radiation intensity monitoring. The monochromator is manufactured from a Si single crystal and contains a set of periodically spaced slit openings oriented in parallel to the diffraction plane. The data of reflectivity and transparency measurements obtained by scanning the diaphragm perpendicular to the measurement plane are presented and compared with the results of computer simulation.
