Graphite monochromator
WebA pyrolytic graphite monochromator provides a 4.22 Å, with a beryllium filter to eliminate higher order wavelengths. The Detectors Group in the Neutron Technologies Division operates the beamline. Recent efforts include calibration of Anger cameras for diffraction beamlines, testing of the new dome Anger camera prototype assembly ... WebFig. 2 shows the X-ray diffraction pattern and qualitative analysis results for Fe oxide, measured using a graphite monochromator. By using a graphite monochromator, it is possible to obtain an X-ray diffraction pattern with an extremely low background, and thereby detect trace components. 4000 Apparatus and Measurement conditions

http://www.sb.fsu.edu/~soma/monochrm.html WebFor X-ray investigations, a few drops of each sample of interest (FFF fractions 1, 2) were deposited onto a recessed silicon glass and allowed to dry. X-ray powder diffraction analyses were carried out by means of a Philips X’Celerator powder diffractometer equipped with a graphite monochromator in the diffracted beam.
WebA monochromatic is selected from the incoming white beam using a monochromator crystal. A monochromator is a single- crystal that selects the neutron wavelength according to Bragg's lawn 2dsin [1]. The range of wavelengths accepted depends on the crystal structure and its mosaicity. WebSep 30, 2004 · The selected crystal of [Cd(H 2 O) 2 (ο-HOC 6 H 4 COO) 2] 2 was mounted on an Rigaku Raxis-IV diffractometer using Mo-Kα radiation (λ = 0.71073 Å, T = 293 K) with a graphite monochromator. Intensities were corrected for Lorentz and polarization effects and empirical absorption, and the data reduction using the SADABS program [ 16 ].
