Two data sets were collected on single crystals of hexamethylenetetramine (urotropin) using a fourcircle diffractometer with Cu K~ radiation and an imaging-plate two-dimensional detector with Mo K~ source using the rotation method. Both data sets extend to the same limit of sin 0/2 = 0.62A -~, corresponding to a resolution of 0.81 ,&. Different processing protocols were employed for the two set...

The fundamental parameters approach to line profile fitting uses physically based models to generate the line profile shapes. Fundamental parameters profile fitting (FPPF) has been used to synthesize and fit data from both parallel beam and divergent beam diffractometers. The refined parameters are determined by the diffractometer configuration. In a divergent beam diffractometer these include ...

We have instrumented the 5ID-C hutch of DND-CAT at the Advanced Photon Source (APS) for x-ray surface spectroscopy and scattering. A wide variety of experiments have already been carried out at 5ID-C, including studies on semiconductors, oxides, metals, nanodots, and biomolecular adsorption. We describe the beamline optics, data collection hardware and software, and both diffractometers, a five...

BL-17A is a macromolecular crystallography beamline dedicated to diffraction experiments conducted using micro-crystals and structure determination studies using a lower energy X-ray beam. In these experiments, highly accurate diffraction intensity measurements are definitively important. Since this beamline was constructed, the beamline apparatus has been improved in several ways to enable the...

Beamline I07 at Diamond Light Source is dedicated to the study of the structure of surfaces and interfaces for a wide range of sample types, from soft matter to ultrahigh vacuum. The beamline operates in the energy range 8-30 keV and has two endstations. The first houses a 2+3 diffractometer, which acts as a versatile platform for grazing-incidence techniques including surface X-ray diffraction...

By using hot pressing, plastically bent Si and Ge wafers in cylindrical shape with keeping mirror surfaces have been obtained. In the present paper, the experimental results obtained by diffractometer with channel-cut monochromater have been discussed from the viewpoint of requirements necessary for curved monochromaters for X-ray optics. It was made clear that by choosing appropriate condition...
