Figure 4
The solid and dashed lines are the calculated mirror acceptance and pre-focused beam size at the KB mirror location versus secondary focusing size, for horizontal KB mirror focusing of `pre-underfocused' sources at 18-ID. As a comparison, SHADOW ray-tracing simulations of secondary focusing are also performed for four different pre-focusing conditions, using the KB mirror shapes calculated basing on the phase-space analysis. For simplicity, the secondary focusing sizes are calculated with the focus distance measured from the mirror center.
