Top: the complete optical scheme adopted on ID24, consisting of a pair of mirrors in a Kirkpatrick–Baez geometry (VFM1 and HFM) and the polychromator crystal (PLC). A second vertically focusing mirror (VFM2) downstream of the polychromator is used to refocus the beam onto the sample. Bottom: schematic sequence of the focusing elements on ID24 (see text for details) |
