The design and characterization of a contoured crystal polychromator for energy-dispersive EXAFS is presented. It gives a full spot between 20 and 40 µm full size in the 5–12 keV energy range.

It is shown for the first time that, similar to single-crystal structure analysis, the lack of inversion symmetry has significant impact on the DAFS signal, so that DAFS may contribute to structure analysis as well.

A hydrostatic pressure cell (maximum pressure 700 MPa) with synthetic diamond windows is applied to quantitatively measure small-angle X-ray scattering of lysozyme at high pressure.

These DOS-Windows running programs for X-ray absorption analysis are written to give the user a tool to undertake all steps of data processing and modelling, rather than making use of the most recent programming facilities. They are in use at the Collaborative Research Group on Interfaces, at the ESRF in Grenoble, France.

The first XMCD measurements carried out on the ID24 energy-dispersive XAS beamline at the ESRF are reported. Circular-polarized X-rays are obtained using perfect diamond crystals as quarter-wave plates.

X-ray reflectivity measurements with a synchrotron radiation source were carried out for thin polymer films on a glass plate. The film thickness and surface and interface roughnesses were determined by curve fitting and Fourier transform procedures.

The deformation electron densities (Δρ) have been determined for synthetic orthoferrites, RFeO3 (R = Y, Ho), using both scintillation and fast avalanche photodiode (APD) detectors for focused synchrotron X-radiation at wavelengths of 0.70 and 0.84 Å. The APD Δρ images indicate strongly that the electron density is perturbed significantly by the cation–cation magnetic interactions.
