Nanofocused x-ray photon correlation spectroscopy

Physical Review Research, 2022
Here, we demonstrate an experimental proof of concept for nanofocused x-ray photon correlation spectroscopy, a technique sensitive to nanoscale fluctuations present in a broad range of systems. The experiment, performed at the NanoMAX beamline at MAX IV,

Cross-correlation analysis of X-ray photon correlation spectroscopy to extract rotational diffusion coefficients. [PDF]

Proc Natl Acad Sci U S A, 2021
Significance X-ray photon correlation spectroscopy (XPCS) is a powerful technique that can probe a broad range of space and time scales and will become increasingly powerful due to coming advancements in coherence. Assessing translational and rotational diffusion is a key quantity in analyzing material structures and dynamics, with ...

X-Ray Photon Correlation Spectroscopy with Coherent Nanobeams: A Numerical Study [PDF]

Crystals, 2020
X-ray photon correlation spectroscopy accesses a wide variety of dynamic phenomena at the nanoscale by studying the temporal correlations among photons that are scattered by a material in dynamical equilibrium when it is illuminated with a coherent X-ray

MHz X-ray photon correlation spectroscopy using an acoustic levitator at the European XFEL [PDF]

Journal of Synchrotron Radiation
The structural and dynamical properties of soft-matter systems play an important role in crystallization and nucleation theory. Despite their significance, the dynamical properties are still poorly understood because of experimental constraints and the ...

Nanosecond X-ray photon correlation spectroscopy using pulse time structure of a storage-ring source [PDF]

IUCrJ, 2021
X-ray photon correlation spectroscopy (XPCS) is a routine technique to study slow dynamics in complex systems at storage-ring sources. Achieving nanosecond time resolution with the conventional XPCS technique is, however, still an experimentally ...

On the use of two-time correlation functions for X-ray photon correlation spectroscopy data analysis. [PDF]

J Appl Crystallogr, 2017
Multi-time correlation functions are especially well suited to study non-equilibrium processes. In particular, two-time correlation functions are widely used in X-ray photon correlation experiments on systems out of equilibrium. One-time correlations are often extracted from two-time correlation functions at different sample ages.

Non-uniform interval-pulse X-ray photon correlation spectroscopy for reduced exposure [PDF]

Journal of Synchrotron Radiation
X-ray photon correlation spectroscopy (XPCS) is a powerful technique for evaluating microscopic dynamics using coherent X-rays. Detecting fast or small-scale dynamics typically requires strong illumination and wide-angle scattering detection; however ...

Split-pulse X-ray photon correlation spectroscopy with seeded X-rays from X-ray laser to study atomic-level dynamics [PDF]

Nature Communications, 2020
Here the authors study atomic scale dynamics in water by using X-ray photon correlation spectroscopy. They use a split-and-delay optics with self-seeding of X-rays to generate pulses of enough energy and controlled time delay between two X-ray pulses.
