(a) XAS data collected for each shot (dots) normalized to the incoming X-ray (I0) from IPM3 (scatter plot) where pre-edge and edge regions, from 6530 eV to 6621.5 eV, are shown in blue and the shape resonance, from 6623 eV to 6798.3 eV, is shown in orange. The red line is the mean of the data for each energy point. (b) Incoming X-ray (I0) intensity measured at IPM3 after the monochromator as a function of the X-ray energy. By adjusting the central energy of the FEL during the energy scan, the beam intensity after the monochromator was kept roughly constant.
