[Cover illustration] Cover illustration: Difference intensities in small-angle scattering from laser-excited gold nanoparticles in water at delays of 300 ps (left) and 1 µs (right), which show the signatures of expanding vapor bubbles and the particle morphology (see Plech, Kotaidis, Istomin and Wulff, pages 288-294). The graph shows the radially integrated data for a set of increasing laser fluences and accordingly growing vapor bubbles.

The Beamline X28C of the Center for Synchrotron Biosciences: a National Resource for Biomolecular Structure and Dynamics Experiments Using Synchrotron Footprinting

S. Gupta, M. Sullivan, J. Toomey, J. Kiselar and M. R. Chance

Synopsis: Beamline X28C, at the National Synchrotron Light Source of Brookhaven National Laboratory, functions as a platform for synchrotron footprinting research for structural mapping of proteins and nucleic acids. The article provides a summary of the X28C beamline technology, published results and defines protocols for its adoption at other synchrotron facilities.

The small-angle and wide-angle X-ray scattering set-up at beamline BL9 of DELTA

C. Krywka, C. Sternemann, M. Paulus, N. Javid, R. Winter, A. Al-Sawalmih, S. Yi, D. Raabe and M. Tolan

Synopsis: The new set-up for small-angle and wide-angle X-ray scattering at beamline BL9 of the Dortmund Electron Accelerator (DELTA) is presented. First measurements of small-angle X-ray scattering on lysozyme solutions and a study of crystallographic texture of [alpha]-chitin and calcite in lobster and crab shell are discussed.

Zr and Ba edge phenomena in the scintillation intensity of fluorozirconate-based glass-ceramic X-ray detectors

B. Henke, S. Schweizer, J. A. Johnson and D. T. Keane

Synopsis: Optically activated fluorozirconate-based glass ceramics are promising candidates as X-ray detectors. The influence of the glass matrix on the scintillation properties of the embedded nanocrystals is investigated as a function of X-ray energy, particle size and structure of the embedded nanocrystals.

Element-selective X-ray detected magnetic resonance: a novel application of synchrotron radiation

J. Goulon, A. Rogalev, F. Wilhelm, Ch. Goulon-Ginet and G. Goujon

Synopsis: X-ray detected magnetic resonance (XDMR) is a new element-selective spectroscopy in which X-ray magnetic circular dichroism is used to probe the resonant precession of spin and orbital magnetization components when a strong microwave pump field is applied perpendicularly to the static bias field. Experimental configurations and instrumentation suitable to detect the very weak XDMR signal are compared. XDMR data collected at both the spin-orbit split Y L-edges and at the Fe K-edge on yttrium iron garnet films are shown to yield unique information regarding the precession dynamics of induced spin and orbital components.

Application of glancing-emergent-angle fluorescence for polarized XAFS studies of single crystals

A. I. Frenkel, D. M. Pease, J. I. Budnick, P. Shanthakumar and T. Huang

Synopsis: The glancing-emergent-angle (GEA) method of fluorescence detection has been applied for polarized XAFS studies of single crystals of Cr-doped vanadium sesquioxides. The GEA method is non-destructive, suitable for in situ studies of single crystals and is thus a significant improvement over their powder analysis.
