Quick X-ray reflectometry in simultaneous multiwavelength dispersive mode

Extended X-ray absorption fine structure in dispersive mode

2014 It has been possible to disperse the X-ray beam provided by the storage ring DCI at LURE in order to perform fast EXAFS experiments (~ 1 s). The weak divergence of the synchrotron beam opens up the possibility of achieving a very good energy resolution. The first data collected with a solid-state detector array (RETICON) show that kinetic studies with a time scale lower than 1/10 s could b...

Curvature effect in grazing X-ray reflectometry

Grazing X-ray reflectometry is currently used for the characterization of thin layer

Multiwavelength Observations of Ultraluminous X-Ray Sources

Multiwavelength observations may help us understand the physical nature of the ultraluminous X-ray sources (ULXs) found in external galaxies. Enabled by the arcsecond X-ray source positions now available from Chandra, there has been significant recent progress in the identification of optical and radio counterparts to ULXs. Recent results are reviewed on the identification of optical stellar co...

Energy-dispersive X-ray emission spectroscopy using an X-ray free-electron laser in a shot-by-shot mode.

The ultrabright femtosecond X-ray pulses provided by X-ray free-electron lasers open capabilities for studying the structure and dynamics of a wide variety of systems beyond what is possible with synchrotron sources. Recently, this "probe-before-destroy" approach has been demonstrated for atomic structure determination by serial X-ray diffraction of microcrystals. There has been the question wh...
