Figure 5
Schematic layout of the sector 3 beamline at the APS showing a combination of focusing elements (toroidal and KB mirrors) and their focal points at the D-station. f1 and f2 are the source and image distances for the toroidal mirror. f3 and f4 are the source and image distances for the KB mirrors. Beam sizes in their respective positions are simulated by the program package XOP in a 2 mm × 2 mm box to show the impact of the achieved focusing. Simulations presented in this figure were made considering the slope errors of the existing toroidal mirror and KB mirrors; the beam size grew from 4.5 µm (H) × 0.6 µm (V) to about 13.5 µm (H) × 6.3 µm (V) at the sample position.
