XAS Beamline

ANKA-XAS is a high performance X-ray absorption spectroscopy (XAS) beamline on a bending
magnet source at ANKA.
Due to the reasonable high flux the beamline is suited for highly diluted systems in bulk samples.


Dedication, Scientific Applications
XAS provides essential information about the local atomic geometry and the chemical state of the absorbing atom. The method is element specific and is not restricted to the crystalline phase, but may be used with highly disordered amorphous and liquid samples. The power and versatility of the technique has meant that XAS has increasingly become a valued experimental tool for many, including non-specialist, users from different research areas. A cooperative multidisciplinary scientific program involving ISS and other research groups will be established at ANKA to use XAS to solve scientific questions in the fields of:

Nanomaterials & catalytic systems
There is intense interest in the development of materials with nano-sized dimensions with novel catalytic, energy storage, or macroscopic properties. Research groups from the Forschungszentrum Karlsruhe (FZK) and external institutions focus eg. on H-storage materials based on Ti-clusters, on catalytic systems as nanostructured traps for SOx , and on Ni-doped nano carbon tube systems for tunable magnetic properties. An objective of characterization is to determine the structure and interatomic distances, and the mean oxidation state of atoms in the nanoparticle. The efficiency of new catalytic systems will be studied in-situ by tracking the changes of the chemical state of educts or products using XAS in combination with eg. mass spectrometer.

Environmental Sciences
Contamination of the environment is an inevitable consequence of industrial and domestic processes and presents a health hazard and an limitation to the productive use of land. Currently research is focused on Zn release to soils, a problem even from such seemingly harmless objects as electricity pylons, and on sulfuric acidification of surface waters, which leads to mobilization of toxic metals in mining areas. XAS is an extremely important tool in identifying the nature of toxic metals causing the contamination and, thus allowing remedial strategies to be devised.ausing the contamination and, thus allowing remedial strategies to be devised.

Sample environment

Standard holders (manual) for transmission and fluorescence measurements, e.g., one for 13 mm pellets and one for plates (max. 8 mm thickness, 4 cm length, 5 cm high). A multi sample holder with 12 position (tansmission and fluorescence measurements possible) is available. The sample wheel can be adjusted in both direction perpendicular to the beam.

A sample positioning system from Huber is used for grazing incident XAS and for aligment of heavy equipment (includes z-drive, 2 cradles, phi-rotation and a x-drive). Additional two Huber slits can be used for the grazing incident measurements.

The ANKA-XAS beamline spans the energy range from 2.4 to 27 keV. This covers the K-edges from S to Cd, and up to the L-edge of U, enabling speciation studies of catalytically and environmentally important elements like sulfur. The double crystal monochromator design allows exchange of the two parallel mounted Si(111) and Si(311) crystal pairs within minutes. The key parameters of the beamline are summarized in table.
