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 10(8) photons s(-1) up to 10(10) 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 micro m accuracy over a 120 mm stroke. The beamline has been fully characterized and the first results are presented.
