Figure 3
Resolution improvement by dispersion compensation. The measured peak widths (open circles) are plotted as obtained from a calibration Fe powder sample using dispersion compensation as shown in Fig. 2. The solid line indicates the resolution as calculated from the experimental parameters. Contributions to the total resolution arise from the sample thickness (long dashes), detectors slit opening (short dashes) and dispersion contribution (dashed-dotted). The minimum around the [220] reflection results from the dispersion compensation. |
