Energy range covered by the multicrystal monochromator. The intrinsic energy resolution dE/E is calculated for the symmetrical Bragg case and linear σ-polarization. The values for Be(002) refer to a 200 µrad mosaic crystal. The intrinsic energy resolution for (111) reflection from a (100)-oriented diamond in asymmetric Laue geometry is dE/E = 46 × 10−6 at 9 keV. For incident π-polarization the polarization factor cos(2θ) has to be taken into account. |
