Title: A Beam line for Macromolecular Crystallography in ALBA

Abstract

ALBA is a third generation 3 GeV storage ring being built near Barcelona and foreseen to be operational in 2010. Out of the seven beamlines already funded in ALBA, one will be dedicated to macromolecular crystallography (MX). The beamline, dubbed XALOC, shall cope with a broad range of crystal structures and sizes. To this aim, a flexible optical design involving variable focusing optics has been incorporated into the beamline optics. The photon source will be a 2 m long, in-vacuum undulator with a period of 21.3 mm. The optics will consist in a Si(111), double-crystal monochromator cryogenically cooled, and a pair of mirrors placed in a Kirkpatrick-Baez configuration. The beamline will deliver a high flux beam in the 5-15 keV energy range, with an energy resolution of {delta}E/E {approx}2 x 10-4. In addition to the main beamline, it is being considered the possibility to use a diamond laue monochromator to provide photons at a fixed wavelength to an ancillary branch. This report shows the present status of the beamline design.

  • A new instrument (Station 9.5) has been established on the wiggler line at the Daresbury Synchrotron Radiation Source (SRS). It extends the experimental capability at Daresbury for macromolecular crystallography beyond what is provided for with Stations 7.2 (Ref. 1), 9.6 (Ref. 2), and 9.7 by providing a point focused white beam (from a Pt-coated toroid mirror) and/or a rapidly tunable monochromatic beam (using a water-cooled double-crystal monochromator) (Ref. 3). The design principles of the new Station 9.5 have been published (Ref. 4). A CCD detector for the station is being developed (preliminary work is described in Ref. 5, or seemore » the additional poster at this meeting) to allow time slices of part of a diffraction pattern to be measured. Laue patterns are currently recorded on film, but access to an image plate detector will shortly become available. Shutter speeds down to 50 {mu}s are routinely available using a rotating disk shutter (Ref. 6). Fluorescence detectors are available for optimized anomalous dispersion data collection. The experimental bench is long enough to accommodate a camera system, and downstream from it an on-line'' image plate scanner. Data collected on the instrument in various modes of operation will be described for a variety of macro and small molecule crystal systems.« less
  • Neutron crystal diffraction experiments are complementary to x-ray diffraction studies of macromolecules because neutrons are strongly scattered by hydrogen and/or deuterium and can therefore be used to locate these atoms directly in a macromolecule. Since hydrogen atoms constitute about half of the total number of atoms in a macromolecule, and are functionally and structurally important in determining the biological properties of the system, a detailed knowledge of their location can often provide unique information about the system under study. However, because of the relatively low flux (on the order of 10{sup 6} neutrons/s/cm{sup 2}) of neutrons available at the highestmore » flux steady-state reactors, high resolution diffraction experiments require large crystals and long data collection times. Typical crystal volumes exceed a cubic millimeter and data collection times approach three to four months to collect complete data to atomic resolution. Because of these limitations, relatively few high resolution neutron structures have been completed to date. To improve data collection efficiency and throughput, we have redesigned the macromolecular neutron crystallography beam line (H3A) at Brookhaven National Laboratory{close_quote}s high flux beam reactor. In this report, the new facility is described. {copyright} {ital 1996 American Institute of Physics.}« less
  • An overview is presented of the x-ray optics of the four macromolecular crystallography beam lines under construction at the storage ring SIBERIA-2, Moscow. The four workstations are to utilize isomorphous replacement, anomalous dispersion, reflections energy profile, and the Laue technique. The instrumentation details, the results of ray-tracing analysis, and the use of an area detector are discussed.
  • A practical method for operating existing undulator synchrotron beamlines at photon energies considerably higher than their standard operating range is described and applied at beamline 19-ID of the Structural Biology Center at the Advanced Photon Source enabling operation at 30 keV. Adjustments to the undulator spectrum were critical to enhance the 30 keV flux while reducing the lower- and higher-energy harmonic contamination. A Pd-coated mirror and Al attenuators acted as effective low- and high-bandpass filters. The resulting flux at 30 keV, although significantly lower than with X-ray optics designed and optimized for this energy, allowed for accurate data collection onmore » crystals of the small protein crambin to 0.38 Å resolution.« less
