The macromolecular crystallography station at beamline BM16 at the ESRF

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.

“…A complete description of the beamline is reported elsewhere. 15 Data were indexed, integrated, and scaled using the HKL2000 program. A single crystal of compound 7 was mounted on a Bruker four-circle kappa-diffractometer equipped with a Cu INCOATEC microsource operated at 30 W power (45 kV, 0.60 mA) to generate Cu Kα radiation (λ = 1.54178 Å) and a Bruker AXIOM area detector (microgap technology).…”

“…For compound 3 , X-ray diffraction data on a single crystal of dimensions 0.08 × 0.02 × 0.02 mm 3 were collected at the ESRF synchrotron in the Spanish BM16 beamline (Grenoble, France) using λ = 0.7378 Å at 100 K. The oscillation of the sample was performed with a single axis Huber 410 diffractometer equipped with an ADSC Q210r CCD detector. A complete description of the beamline is reported elsewhere . Data were indexed, integrated, and scaled using the HKL2000 program …”

“…Single Crystal X-ray Diffraction (SCXRD). X-ray diffraction measurements were conducted using synchrotron radiation (Table 1) at the BM16 Spanish beamline 45 at ESRF, making phi scans when collecting the data. Data sets of 360 (or 180) images were collected in a ADSCq210r CCD detector.…”

“…All the experiments were performed at the BM16-CRG beamline at the ESRF (Grenoble, France) (Juanhuix et al, 2005). The principal optical elements of this line are a primary Rh-coated flat mirror limiting the energy range to 17 keV and producing vertical collimation, a Si(111) double-crystal monochromator and a secondary Rh-coated toroidal mirror focusing the monochromatic beam horizontally and vertically at the sample position.…”
