Commissioning and first results of the LNLS XAFS beamline

An X‐ray absorption fine‐structure spectroscopy beamline has been installed and commissioned at a bending‐magnet source at LNLS. Three monochromators are available: a channel‐cut, a double‐crystal and a four‐crystal set‐up. They have been operated from 2500 up to 15000 eV, with a resolving power better than 5500 in the full range. Photon flux of the order of 108 photons s−1 up to 1010 photons s−1 has been attained. The experimental station is equipped with a table that can withstand a weight of 300 kg and track the vertical position of the beam with a 2.5 µm accuracy over a 120 mm stroke. The beamline has been fully characterized and the first results are presented.
