Design of a Four-Crystal Monochromator Beamline for Radiometry at BESSY II

M. Krumrey

Synopsis: The beamline will provide radiation with tunable photon energies from 1.75 keV to 10 keV and high spectral purity for radiometric calibrations and other applications.

Submicrometre Beams from a Hard X-ray Waveguide at a Third-Generation Synchrotron Radiation Source

A. Cedola, S. Lagomarsino, S. Di Fonzo, W. Jark, C. Riekel and P. Deschamps

Synopsis: The use of an X-ray waveguide for scattering and diffraction experiments at an ESRF undulator is discussed. A maximum flux of 8 × 10⁹photons s^-1 at [lambda] = 0.083nm was obtained with a multilayer monochromator. The combination of an Si (111) monochromator and ellipsoidal mirror resulted in a flux of 1 × 10⁹photons s^-1 in a 0.15 × 30 [mu] m² beam.

A Novel Approach to Extract Morphological Variables in Crystalline Polymers from Time-Resolved Synchrotron SAXS Data

B. S. Hsiao and R. K. Verma

Synopsis: A novel approach has been developed to analyze time- resolved SAXS data using correlation function and interface distribution function methods. It has been demonstrated that detailed time-dependent morphological variables can be extracted from PET crystallization using this approach.

Statistical Analysis of X-ray Speckle at the NSLS

O. K. C. Tsui, S. G. J. Mochrie and L. E. Berman

Synopsis: Measurements, carried out at beamline X25 at the National Synchrotron Light Source, of X-ray speckle produced by an aerogel sample are presented. A statistical analysis of the speckle intensity is performed and compared with what may be expected based on the X25 source dimensions and the optics employed.

Small-Angle X-ray Scattering Using Coherent Undulator Radiation at the ESRF

D. L. Abernathy, G. Grübel, S. Brauer, I. McNulty, G. B. Stephenson, S. G. J. Mochrie, A. R. Sandy, N. Mulders and M. Sutton

Synopsis: A high-coherent-flux X-ray beam for small-angle-scattering studies has been produced and analyzed at the Troïka beamline of the European Synchrotron Radiation Facility. The statistics of a static speckle pattern are used to characterize the coherence properties.

A New Apparatus for Polarized X-ray Absorption Fine Structure Using a Grazing-Incidence Fluorescence Excitation

H. Oyanagi

Synopsis: A new apparatus for polarized X-ray absorption fine structure (XAFS) at low temperature and its applications to local structure studies of high- T_c superconductors and optically excited states, using `pump and probe' XAFS, are described.

Observation of horizontal focusing of X-rays using a toothed-crystal monochromator

J. Hrdý, S. Pascarelli, F. D'Acapito, S. Colonna and S. Mobilio

Synopsis: A new kind of horizontal focusing of X-rays was observed using a toothed-crystal monochromator. The focusing may be attributed to the properties of inclined diffraction.

Application of synchrotron radiation X-ray fluorescence imaging combined with histochemical staining to the renal section of mercury-treated rats

S. Homma-Takeda, Y. Kumagai, M. Shinyashiki and N. Shimojo

Synopsis: A biomedical application of synchrotron radiation comprising X-ray fluorescence imaging and histochemical staining was employed to examine the detailed distribution of metal elements and morphological changes in the kidney section of mercury-treated rats. The spatial resolution was improved to 5 × 5 [mu] m².
