Paper Abstract

A double bounce monochromator with a roughened Si(111) first crystal and a sagitally focusing roughened Si(111) second crystal was tested at a Cornell High Energy Synchrotron Source (CHESS) bending magnet line. Flux and energy width measurements were taken and comparisons are made with measurements from a perfect Si(111) monochromator (also sagitally focused) as well as calculations for flux and energy width for a source-matched monochromator and a mosaic monochromator. For the roughened monochromator at 17 keV, the flux was greater by a factor of 7.5 while the energy spread was only increased by a factor of 2, as compared to the perfect monochromator. These measured increases are consistent with predicted values for source-matched optics. Other advantages of mosaic monochromators in addition to source- matching are discussed.
