Figure 6
Peak intensities (circles) and beam widths (triangles; FWHM) of the beam profiles scanned by BPM2 as functions of the horizontal (H) and vertical (V) slit-openings S1H in (a) and S1V in (b), respectively. Both sets of data deviate from the uniform radiation approximation (dashed fitted lines) at S1H ≃ 0.6 mm (H) and S1V ≃ 0.35 mm (V). Shown in (c) is the approximated radiation source profiles in the vertical and horizontal directions. |
