The ESRF beamline ID26: X-ray absorption on ultra dilute sample.
The ESRF beamline ID26 is dedicated to XAFS studies on Ultra-diluted Samples (XAUS beamline). The spectral range 2.3-30 keV is covered. The aim of the beamline is to extract structural and electronic information on dilute samples for which the concentration of the absorbing element ranges from a few ppm up to 10 000 ppm. A wide range of applications is covered in biology, catalysis, chemistry, environmental sciences, solid state physics, etc. The beamline accepted the first users in November 1997. We give herein a brief description of the beamline and report on recent results.
