Figure 2
The Laue–Bragg monochromator in dispersion-compensating mode. For clarity of presentation, the multilayer which is present in Fig. 1 is omitted. An energy gradient across the focusing divergence is produced by increasing the bending radii such that the source lies off the Rowland circle. Beams indicated by long (short) dashes relate to low (high) energies. By dispersion matching, a parallel beam emerges from the powder-like sample. |
