A 2.3 to 25 keV XAS beamline at LNLS

The LNLS XAS beamline has been operating for external users since July 1997 . Many facilities and improvements have been progressively added to it, ext ending the range of applications. Here, a technical description of the main beamline components is given, and results concerning important points, suc h as available flux at low and high energies, harmonic contamination, energ y resolution and stability, are presented. Some key results are given to de monstrate the beamline performance and limitations. It is shown that the be amline can cover a large energy range, starting from the rather low energy of 2.3 keV up to 25 keV.
