XAS end-station in SOLARIS
In December 2015, the SOLARIS Centre team finished the installation of the PEEM/XAS beamline second end-station.
XAS is a universal station for X-ray absorption spectroscopy. In the soft X-ray energy range it is often termed NEXAFS (Near Edge X-Ray Absorption Fine Structure). This spectroscopy provides element and chemical specificity, as well as sensitivity to polarization effects related to magnetic and crystal structure of the materials by means of XMCD and XMLD effects.
The XAS end station is a UHV system equipped with two-chambers (one for spectroscopy and other for preparation). It features:
- Samples (powder and bulk) fitting a standard flag-style sample holder;
- Beam spot on the sample (h x v): 2 mm x 5 mm;
- Total electron yield (TEY) and total fluorescence yield (TFY) detection modes, giving an information depth of several and a hundred nm, respectively;
- Sample environment from UHV to 10 mbar of Heexchange gas;
- Spectroscopic measurements in a broad temperature range of (20–1300 K) and external magnetic field of 0–1 kOe; angular dependence;
- Fully equipped preparation chamber (comparable to that of the PEEM end-station).
