X-ray powder diffraction at the XRD1 beamline atLNLS

Various upgrades have been completed at the XRD1 beamline at the Brazilian synchrotron light source (LNLS). The upgrades are comprehensive, with changes to both hardware and software, now allowing users of the beamline to conduct X-ray powder diffraction experiments with faster data acquisition times and improved quality. The main beamline parameters and the results obtained for different standards are presented, showing the beamline ability of performing high-quality experiments in transmission geometry. XRD1 operates in the 5.5-14keV range and has a photon flux of 7.8 x 10(9)photonss(-1) (with 100mA) at 12keV, which is one of the typical working energies. At 8keV (the other typical working energy) the photon flux at the sample position is 3.4 x 10(10)photonss(-1) and the energy resolution E/E = 3 x 10(-4).
