Figure 1
Schematic drawing of the ¹⁶⁹Tm HRM setup at PETRA III. Positions of double-crystal monochromator (DCM) and compound refractive lenses (CRLs) are given relative to the central undulator position. The HRM schematic drawing depicts the orientation of the atomic (111) planes in the Si crystals and the effect of the asymmetrical cut crystals on the beam width.
