Measurement geometry and set-up description on ID20. Synchrotron radiation generates photons through the four-undulator insertion device (ID). The photon beam is shaped through slits and a specific wavelength is selected via two monochromators (a pre-monochromator and a channel-cut post-monochromator). The beam is focused down to 10 µm × 20 µm using two KB mirrors onto the sample in the DAC. Spherical crystal analyzers reflect the scattered signal from the sample and diamond. They are used as focusing monochromator enabling a sub-eV (0.7 eV) final resolution. The scattered image is collected on a two-dimensional Maxipix pixel detector, one for each row of the four crystal analyzers.
