Abstract
A beamline previously used for powder diffraction (BM16) at the European Synchrotron Radiation Facility has been redesigned and rebuilt to carry out both mcromolecular crystallography (MX) and noncrystalline diffraction/scattering (NCD/S) experiments. The MX station has become available for routine user experiments since September 2003 and the NCD/S station is currently being commissioned. The optics are designed so that both the focal spot and flux are good in the 6–17keV energy range (2.1–0.73Å), while the performance is optimal at the selenium K-edge (12.658keV,0.98Å). The MX facility is fully equipped to carry out multiwavelength anomalous dispersion experiments, in particular at the SeK-edge. Moreover, experiments using lower energies such as those of the Mn and FeK-edges are also possible. Here we describe the optical configuration and the setup for MX experiments, as well as a typical example of the experiments carried out so far.
