Figure 1
The optical scheme of the energy-dispersive XAS spectrometer. On beamline ID24 the source is a demagnified image of the undulator source (i.e. secondary source). Source-to-crystal distance (p) is equal to 22 or 31 m (depending on the chosen beamline branch), q = 0.6–1.2 m and d = 1.2–2.4 m. |
