A statistical analysis of the static speckle produced by illuminating a disordered aerogel sample by a nominally coherent X-ray beam at wiggler beamline X25 at the National Synchrotron Light Source is reported. The results of the analysis show that the coherence delivered to the X25 hutch is within 35% of what is expected. The rate of coherent photons is approximately two times smaller than expected on the basis of the X25 wiggler source brilliance. 
High wavevector temporal speckle correlations at the Linac Coherent Light Source.
TLDR
It is reported on the feasibility of high wavevector temporal speckle correlation measurements at the world's first hard x-ray free electron laser, the Linac Coherent Light Source, and a potential scheme to deliver a single-mode hardx-ray pulse is proposed by using a narrow bandpass crystal monochromator.

Toward a single mode Free Electron Laser for coherent hard x-ray experiments
The fluctuations of the longitudinal coherence length expected from the world's first hard X-ray Free Electron Laser, the Linac Coherent Light Source, are investigated. We analyze, on a shot-to-shotExpand
Speckle Statistics, Coherence and Polarization of a Collisional Soft X-Ray Laser
A simple model of dynamics of a collisional X-ray laser is given applying Maxwell-Bloch equations in a uniform approximation. The main considered parameters include polarization and coherence of theExpand
Correlation spectroscopy with coherent X-rays
X-ray photon correlation spectroscopy (XPCS) is a novel technique for the study of slow dynamics in disordered materials. It overcomes limitations of visible light scattering techniques such asExpand

A method for reducing time sequences of raw scattering images to intensity time-autocorrelation functions is presented. The procedure is based on the use of a charge coupled device (CCD) areaExpand
Focusing a round coherent beam by spatial filtering the horizontal source.
This paper illustrates the use of spatial filtering with a horizontal slit near the source to enlarge the horizontal coherence in an experimental station and produce a diffraction-limited round focusExpand
Microfocusing transfocator for 1D and 2D compound refractive lenses.
TLDR
An x-ray transfocator design for the combined use of 1D and 2D compound refractive lenses is described and has been implemented at the P10 Coherence Beamline of the PETRA III synchrotron at DESY, Hamburg. Expand
Demonstration of Feasibility of X-Ray Free Electron Laser Studies of Dynamics of Nanoparticles in Entangled Polymer Melts
TLDR
The feasibility of measuring the relaxation dynamics of gold nanoparticles suspended in polymer melts using X-ray photon correlation spectroscopy (XPCS) is demonstrated, and measurements can be realized at slow time scales. Expand
