Figure 4
Phase space results obtained by ray tracing for the four-reflection geometry at 8.500 keV. The abscissa of each plot is the vertical coordinate of each ray, and the ordinate is the vertical divergence of each ray. The upper panel is at the effective source location which is 3.32 m upstream of the grating, and the lower panel is at the grating. These results illustrate how the effective source location was ascertained. That is, the upstream distance was varied until the symmetric diagram shown in the upper panel was the result.
