X-ray Absorption Spectroscopy

X-ray Absorption Spectroscopy beamline optimized for measurements in the tender energy range

SOLABS is a bending magnet beamline dedicated to X-ray absorption fine structure (XAFS) spectroscopy (XAS) in the energy range from 1 keV to 15 keV. The beamline was especially designed for XAFS measurements in the tender X-ray range, i.e., at the K absorption edges of important elements such as P, S, Si, Al and Mg. Besides, the energy range also includes K-edges of heavier elements up to Se, L-edges of elements up to Bi and some M-edges of elements including U, which allows investigation of a variety of highly relevant materials. Due to this straightforward concept without any optical components such as lenses or mirrors, SOLABS can be quickly aligned and easily operated.  At the beamline spectroscopic experiments in different measurement modes and with various sample environments are possible.

XAFS spectroscopy is a non-destructive, element-specific characterization method that can be applied to both crystalline and amorphous materials, liquids and samples in the gas phase.

Technical Specifications and Sample Environment

The spectra can be recorded in transmission, fluorescence and electron yield measurement modes. The measurements can be performed under vacuum conditions and in the presence of the selected gases (He, Ar, O2, N2, CO2) at a pressure equal or lower than atmospheric pressure.

Detailed information about the SOLABS beamline and the features of its end station can be found on the beamline’s home page.

The SOLABS beamline is still under commissioning and it may influence overall beamline performance. We can not guarantee the functionality of all features of the end station and all beam parameters which may differ from the theoretical ones during the experiment.
