Two-Plane Focusing of 30 keV Undulator Radiation

An experimental and theoretical investigation is made of a two-plane focusing refractive lens using undulator radiation in the hard X-ray range.

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

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.

Soft X-ray Beamline Specialized for Actinides and Radioactive Materials Equipped with a Variably Polarizing Undulator

A soft X-ray beamline with a variably polarizing undulator has been designed at SPring-8 to be used for photoemission spectroscopy, focusing on actinide compounds as well as unsealed radioactive materials.

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

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 λ = 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 μm² beam.

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

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

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

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

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

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

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 μm².
