Photon correlation spectroscopy with high-energy coherent x rays

Physical Review E, 2003
We performed x-ray photon correlation spectroscopy on a model suspension of colloidal particles using x rays of three different energies, namely, 8 keV, 13.5 keV, and 19 keV. The observed reduction in the degree of coherence with increasing x-ray energy, as measured by the contrast of the correlation functions, is consistent with theoretical estimates.

X‐ray Photon Correlation Spectroscopy Studies of Surfaces and Thin Films

Advanced Materials, 2014
The technique of X‐ray Photon Correlation Spectroscopy (XPCS) is reviewed as a method for studying the relatively slow dynamics of materials on time scales ranging from microseconds to thousands of seconds and length scales ranging from microns down to nanometers. We focus on the application of this technique to study dynamical fluctuations of surfaces,

A novel event correlation scheme for X-ray photon correlation spectroscopy

Journal of Applied Crystallography, 2012
X-ray photon correlation spectroscopy (XPCS) was employed to measure the time-dependent intermediate scattering function in an organic molecular glass former. Slow translational dynamics were probed in the glassy state and the correlation functions were calculated from two-dimensional speckle patterns recorded by a CCD detector.

Development of ultra-small-angle X-ray scattering–X-ray photon correlation spectroscopy

Journal of Applied Crystallography, 2011
This paper describes the development of ultra-small-angle X-ray scattering–X-ray photon correlation spectroscopy (USAXS–XPCS). This technique takes advantage of Bonse–Hart crystal optics and is capable of probing the long-time-scale equilibrium and non-equilibrium dynamics of optically opaque materials with prominent features in a scattering vector ...
