    An analytical model was constructed of a single silicon crystal monochromator. This model was used to examine the heat transfer processes within the monochromator. It was discovered that extracting heat from the top surface of the monochromator could cause the peak temperature to be below the...

    An x-ray monochromator for the range from 800 eV to 10 keV has been designed, constructed, and tested at LNLS. The high resolution is achieved by a four-crystal scheme where two nondispersive double crystals (or channel-cut crystals) are arranged in the dispersive configuration. Each double...

    A Si(220) double-crystal monochromator for the energy range 10-30 keV is presented. It will be used for EXAFS as well as powder diffraction measurements. To determine the requirements for this monochromator we looked, apart from mean considerations, at the requirements dictated by EXAFS in...

    A possible design for a spherical grating monochromator is based on the translation of the entrance slit in order to minimize the system aberrations during the wavelength scan. This configuration has been studied both analytically and by means of extended ray-tracing calculations and the design...

    Performance of a 24-m spherical grating monochromator is described. This beamline is composed of a prefocusing toroidal mirror, a spherical grating monochromator with a movable exit slit and refocusing mirrors.
