Figure 6
Vertical and horizontal divergence of the exit beam. Top panel: symbols show ray-tracing results for vertical source sizes of 1 µm (circles), 3 µm (squares) and 5 µm (diamonds). The solid lines are Gaussian fits with vertical FWHM widths of 11.2 µrad, 33.5 µrad and 56 µrad. The dashed line is the angular acceptance of the 14.4 keV 1 meV-resolution monochromator operating at 3-ID. Bottom panel: symbols show ray-tracing results for horizontal source sizes of 50 µm (circles) and 100 µm (squares). The solid lines are Gaussian fits with horizontal FWHM widths of 210 µrad and 420 µrad.
