Diamond double-crystal monochromator in Bragg geometry installed on BL-11XU at SPring-8
Abstract
We present here the feature of the diamond double-crystal monochromator in Bragg geometry installed on a standard undulator beamline at SPring-8. The crystal was manufactured by Sumitomo Electric Industries, Ltd., whose size was 8.6 mm ( w) ×3.5 mm ( l) ×0.35 mm ( t) for the first crystal and 10 mm ( w) ×4.7 mm ( l) ×0.39 mm ( t) for the second. The feature of the monochromator was tested by rocking curve measurements as a function of the total power and of the energy that impinged on the crystal. As a result, no significant increase of the full-width at half-maximum was observed up to a total power of 330 W on the first crystal. We discuss the experimental results with the comparison to the calculated FWHM with use of the beamline parameters.
