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.

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.

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 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.
