Figure 4
XAS spectra of a golden grid measured with four different strategies: SBS indicates a step-by-step spectrum measured in picoamperes (left-hand axis). The other three scans, measured in arbitrary units (right-hand axis) correspond to: HCS-EU, existing hard scan in encoder step units; HCS-TRM, HCS scan with the undulator gap fixed and the TRANSFORMER layer applied for the monochromator only; HCS-TRUM, the result obtained for a gap scan with software synchronization between the undulator and the monochromator and the TRANSFORMER layer used to set both undulator and monochromator. Difference spectra (multiplied by 2) used for the quantitative analysis are also displayed (see text for details).
