Hard X-ray Scattering

There are four beamlines dedicated to single-crystal, powder and thin-film scattering and diffraction investigations.
Three of these beamlines (SCD, PDIFF and MPI) are located at bending magnets, the fourth, NANO, is situated at an insertion device source. Typically the beamlines provide X-rays in the energy range between approximately 5 keV and 21 keV. Focusing optics (mirrors, bent monochromators) allow typical beam sizes in the sub-millimeter (full-width at half maximum) range to be achieved.

The experimental stations offer a variety of sample and scattering geometries as well as sample-environmental infrastructure (customised chambers, furnaces, cryostats etc.) to investigate both bulk and near-surface crystallographic and supramolecular structure in a wide range of applied and fundamental materials research areas.
