Higher one-dimensional beam expansion/compression is achievable using larger angles of asymmetry at the expense of a decrease in the total intensity. To increase the intensity, a linearly graded Ge-rich GexSi1-x single crystal was used to prepare a monochromator with 15deg asymmetry angles (total expansion/compression factor of 21) for Cu K[alpha]1 radiation. The X-ray diffraction measurements show more than three times higher peak intensity at the output compared with that of a pure Ge monochromator. ER -
