Unfocused beam

Here is the beam profile measured at the XAS station and at 11 keV. This was measured by rastering a 0.125 pinhole through the beam.  The plot shows 1000*It/I0.  Note the computed horizontal structure of the beam shows through -- the instensity distribution is bimodal with peaks at about +/- 4.5 mm from the center.
