(a) The conventional optical scheme for ED-XAS. A source with a large divergence is used to maximize the footprint of the beam on the polychromator crystal (PLC). (b) The non-conventional optical scheme adopted on ID24, where a collimated undulator source is used. The necessary horizontal divergence is created using a strongly focusing mirror (HFM) upstream of the polychromator crystal.
