Nanometer-scale characterization of laser-driven compression, shocks, and phase transitions, by x-ray scattering using free electron lasers [PDF]

, 2017
We study the feasibility of using small angle X-ray scattering (SAXS) as a new experimental diagnostic for intense laser-solid interactions. By using X-ray pulses from a hard X-ray free electron laser, we can simultaneously achieve nanometer and ...

Analysis of nanostructures based on diffraction of X-ray radiation [PDF]

, 2014
Two topics are considered: (i) the analysis of time-resolved in situ X-ray diffraction studies of free-standing self-catalyzed GaAs nanowires grown on Si-111 (with a focus on the wurtzite zinc blende polytypism) and (ii) detailed investigations of ...

Characterization of Spatial Coherence of Synchrotron Radiation with Non-Redundant Arrays of Apertures

, 2014
We present a method to characterize the spatial coherence of soft X-ray radiation from a single diffraction pattern. The technique is based on scattering from non-redundant arrays (NRA) of slits and records the degree of spatial coherence at several ...
