Full in vacuum multi-purpose endstation for the SUL Beamline at ANKA

The x-ray beamline of the Synchrotron Laboratory for Environmental Studies (Synchrotron Umwelt-Labor SUL) combines sequential diffraction-, absorption- and fluorescence measurements with microfocusing capabilities.

Environmental samples are generally complex (e.g., contaminated soils, mining dump sediments), consisting of mixtures of mineral phases (amorphous, crystalline, with micrometer or nano-scale particle sizes), microbes, and in some cases vegetable material. Spatial distribution, speciation, and phase association of trace levels of contaminants are the basis for risk assessment and development of remediation strategies (e.g. arsenic speciation and distribution in groundwater related sediments). This problem is best addressed by synchrotron based techniques capable of providing spatial resolution in the micrometer range while allowing the combination of microfocused techniques (XRF, XAS, XRD, IR), as foreseen in the SUL concept.
