A high-precision diffractometer has been developed for the structure analysis of a submicrometre-scale single grain of a powder sample at the SPring-8 BL40XU undulator beamline. The key design concept is the combination of a stable focused synchrotron radiation beam and the precise axis control of the diffractometer, which allows accurate diffraction intensity data of a submicrometre-scale sing...

The silicide Sc2RuSi2 was synthesized from the elements by arc-melting. The structure was refined on the basis of single crystal X-ray diffractometer data: Sc2CoSi2 type, * Manuscript Click here to view linked References

We investigate the use of an Amptek Cool-X X-ray Generator for an instructional tool in the physics of x-rays, as well as a source for x-rays for crystal diffraction experiments. The x-ray source is a solid-state two-phase air-cooled source with a timevarying photon output. Two detectors are used in this experiment, the first being an Amptek X-123 Spectrometer and the second a combination scint...

The IBARAKI biological crystal diffractometer, iBIX, is a high-performance time-of-flight neutron single-crystal diffractometer for elucidating mainly the hydrogen, protonation and hydration structures of biological macromolecules in various life processes. Since the end of 2008, iBIX has been available to users' experiments supported by Ibaraki University. Since August 2012, an upgrade of the ...

A general model for the axial divergence aberration function has been developed for a conventional X-ray powder diffractometer equipped with either incidentbeam and/or diffracted-beam Soller slits. In this model, the axial divergence function is generated from the geometrical dimensions of the diffractometer system, which include the axial lengths of the X-ray source, sample and receiving slit ...

A new high-resolution parallel beam X-ray powder diffractometer incorporating multilayer Xray optics in the incident and diffracted beams was constructed and used to refine the crystal structures of several three-layer Aurivillius ceramics using the Rietveld method. The intent of this study was to determine the feasibility of parallel beam data in a research environment. These results were comp...

The x-ray scattering from liquid copper, silver, tin, and mercury was measured at temperatures of 1125 °C, 1050 °C, 335 °C, and 28 °C, respectively, from the open surface of horizontal samples using a focusing theta-theta diffractometer, quartz crystal monochromator positioned in the dif­ fracted beam, scintillation detector, and pulse height discriminator. The effect on the measured intensitie...
