The new third-generation synchrotron radiation source PETRA III located at the Deutsches
Elektronen-Synchrotron DESY in Hamburg, Germany, has been operational since the
second half of 2009. PETRA III is designed to deliver hard X-ray beams with very high
brilliance. As one of the first beamlines of PETRA III the high-resolution diffraction beamline
P08 is fully operational. P08 is specialized in X-ray scattering and diffraction experiments on
solids and liquids where extreme high resolution in reciprocal space is required. The …

Lipid monolayers are widely used as model systems for biomembranes. Their study yields
precious knowledge about the materials used, and may serve to understand some functions
of biomembranes. Grazing Incidence X-ray Diffraction (GIXD) and Total Reflection X-ray
Fluorescence (TRXF) experiments report on structural details, meaning the lateral
organisation of the material on atomic scale, and even atomic composition. The analysis of
GIXD data provides the crystallographic in-plane order of the film, and, depending on the …
