A system for the simultaneous measurement of small-angle X-ray scattering and wide-angle X-ray diffraction (SAXS–WAXD) and the thickness of a coating film, obtained with an automatic coater, during film formation has been developed. The system was installed on beamline BL03XU at SPring-8. As model specimens, poly(methyl methacrylate)-b-poly(n-butyl acrylate)-b-poly(methyl methacrylate) (PMMA-b-...

We studied the X-ray dust scattering halos around 17 bright X-ray point sources using Chandra data. All sources were observed with the Advanced CCD Imaging Spectrometer and High-Energy Transmission Grating in Continuous Clocking Mode (CC-mode) or Timed Exposure Mode (TE-mode). We use an iterative method to resolve the halos at small scattering angles from the zeroth order data in CC-mode or the...

We present resonant inelastic x-ray scattering and x-ray emission spectroscopy results on Gd metal to 113 GPa which suggest Kondo-like aspects in the delocalization of 4f electrons. Analysis of the resonant inelastic x-ray scattering data reveals a prolonged and continuous delocalization with volume throughout the entire pressure range, so that the volume-collapse transition at 59 GPa is only p...

A bent-crystal spectrometer based on the Rowland circle geometry has been installed and tested on the BM30b/FAME beamline at the European Synchrotron Radiation Facility to improve its performances. The energy resolution of the spectrometer allows different kinds of measurements to be performed, including X-ray absorption spectroscopy, resonant inelastic X-ray scattering and X-ray Raman scatteri...

Here we present a review of x-ray absorption spectroscopy and x-ray Raman scattering with the perspective to understand the spectra of water including changes with temperature, mass of the water molecule and presence of monovalent ions. The different detection schemes are discussed and it is concluded that transmission x-ray absorption measurements, using a small area where the thickness is uni...
