parabolically bent multilayers with laterally graded period were applied as condensing reflectors to convert divergent x-rays from laboratory x-ray sources into a parallel beam. Two different modes of coupling such a collimated beam into multi-reflection channel-cut monochromators for high-resolution x-ray diffractometry were tested. Pulsed laser deposition of laterally graded nic-multilayers and their application in parallel beam x-ray optics. Multilayer x-ray optics for energies e 8kev and their application in x-ray analysis. Cut-off reflectors, which allow obtaining a reflected beam with almost no high energy radiation, as well as different monochromator devices that reflect a beam of monoenergetic and polarized radiation are the most widely employed artifacts to perform the excitation radiation improvement in analytical non-expensive tr spectrometers. Metamaterials provide a challenge for materials analysis, as large-scale 3d geometries confound traditional methods. X-ray optics that allow for novel beam geometries and for more efficient use of conventional x-ray sources can be important in defect and structure analysis to close the loop between design and performance. Fortunately, metamaterials have also provided a new variety of array and. a wavelength dispersive xray spectrometer is designed and developed for xray fluorescence analysis and spectroscopy using an xray microprobe at spring8 bl39xu. The spectrometer uses a flat analyzer crystal, and xrays from a small beam spot are dispersed by the crystal onto a position sensitive proportional counter. detectors using foils of 8 cm diameter have exhibited time resolutions of around 200 ps and have operated in the fifi spectrometer in a stable fashion continuously over periods of several months.
