RESUMO
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 5.5-14â keV range and has a photon flux of 7.8 × 109â photonsâ s-1 (with 100â mA) at 12â keV, which is one of the typical working energies. At 8â keV (the other typical working energy) the photon flux at the sample position is 3.4 × 1010â photonsâ s-1 and the energy resolution ΔE/E = 3 × 10-4.
RESUMO
In this report, Py4Syn, an open-source Python-based library for data acquisition, device manipulation, scan routines and other helper functions, is presented. Driven by easy-to-use and scalability ideals, Py4Syn offers control system agnostic solution and high customization level for scans and data output, covering distinct techniques and facilities. Here, most of the library functionalities are described, examples of use are shown and ideas for future implementations are presented.
