Figure 5
Comparisons of vertical profiles of original (a) and collimated (b) beams taken at 65 and 988 m, respectively, from the undulator light source. The dashed lines indicate the best-fit models, consisting of Gaussian and constant components. Each profile is normalized to a maximum of that of the data taken at 65 m, and then in (b) the values were corrected for the throughput of the mirror system. The dash-dotted line indicates the peak values of the original and collimated beams each at 988 m.
