Suite of three protein crystallography beamlines with single superconducting bend magnet as the source

Three near-identical protein crystallography beamlines with a single 6 T peak field superconducting dipole bend magnet as the source have been built at the 1.9 GeV Advanced Light Source. The design and performance of this new facility is described.

CCD-based X-ray area detector for time-resolved diffraction experiments

Fast X-ray area detectors based on the combination of a fast CCD camera with an X-ray image intensifier or with a high-resolution detector have been developed at SPring-8.

Radiation damage to a protein solution, detected by synchrotron X-ray small-angle scattering: dose-related considerations and suppression by cryoprotectants

Radiation damage to a protein solution was investigated by synchrotron X-ray small-angle scattering.

Hysteresis effect in FePd magnetic stripes studied by coherent soft X-ray resonant magnetic scattering

An FePd thin film sample with periodic magnetic stripe domains has been measured with coherent soft x-ray resonant magnetic scattering in reflection geometry. Short exposure to a magnetic field gives a strong change in the observed intensity fluctuations in the scattered magnetic speckle pattern, which indicates a large degree of variation between the two patterns taken before and after field exposure.

The partial Talbot effect and its use in measuring the coherence of synchrotron X-rays

The partial Talbot effect is the self-imaging of some Fourier components of the intensity distribution recorded at specific distances from a periodic object. It provides a convenient quantitative determination of the coherence of the synchrotron radiation beam in the object plane.

Experimental requirements for light-induced reactions in powders investigated by time-resolved X-ray diffraction

A general outline of how to perform a light-excited time-resolved diffraction experiment by applying the optical pump/X-ray probe technique is given.

Synergistic use of synchrotron radiation techniques for biological samples in solution: a case study on protein-ligand recognition by the peroxisomal import receptor Pex5p

SRCD, WAXS and SAXS measured at second-generation synchrotron storage-ring beamlines were used to investigate the structure of a complex of two proteins in solution.

X-ray absorption spectroscopy study of the Li_xFePO₄ cathode during cycling using a novel electrochemical in situ reaction cell

A novel design of the electrochemical in situ reaction cell which can be used for different spectroscopic techniques, long-term X-ray experiments on battery electrodes materials during the lithium-extraction/insertion process, in order to determine the structural perturbations occurring in the system and charge compensation mechanism during cycling.

Small-angle X-ray scattering on the ChemMatCARS beamline at the Advanced Photon Source: a study of shear-induced crystallization in polypropylene

The first ever time-resolved SAXS data collected on the ChemMatCARS beamline are presented, to provide an indication of the current beamline capabilities.

Comments on Treatment of EXAFS data taken in the fluorescence mode in non-linear conditions by G. Ciatto et al. (2004). J. Synchrotron Rad. 11, 278–283

Correcting for fast-channel dead time is suggested as a means for further improving the accuracy of EXAFS data collected under non-linear conditions.

Response to W. K. Warburton's Comments on Treatment of EXAFS data taken in the fluorescence mode in non-linear conditions by G. Ciatto et al. (2004). J. Synchrotron Rad. 11, 278–283

Responses are made to W. K. Warburton's comments in the previous paper concerning the treatment of EXAFS data taken in the fluorescence mode in non-linear conditions presented earlier.
