Comparison of resolution functions. Black circles: APS 3-ID, 2.2 meV FWHM, 21.6 keV. Green diamonds: APS 30-ID, 1.5 meV FWHM, 23.7 keV. Both instruments feature backreflection analyzers. Red squares: M4 instrument calculated as a self-convolution of the measured resolution function of the in-line monochromator operating at APS 3-ID, 1.6 meV FWHM, 14.4 keV. The `bumps' result from the specific combination of asymmetric Bragg reflections of different order. |
