High-pressure X-ray photon correlation spectroscopy at fourth-generation synchrotron sources [PDF]

Journal of Synchrotron Radiation
A new experimental setup combining X-ray photon correlation spectroscopy (XPCS) in the hard X-ray regime and a high-pressure sample environment has been developed to monitor the pressure dependence of the internal motion of complex systems down to the ...

Theory of x-ray photon correlation spectroscopy for multiscale flows

Physical Review Research
Complex multiscale flows associated with instabilities and turbulence are commonly induced under high-energy density (HED) conditions, but accurate measurement of their transport properties has been challenging.

X-ray photon correlation spectroscopy of protein dynamics at nearly diffraction-limited storage rings [PDF]

IUCrJ, 2019
This study explores the possibility of measuring the dynamics of proteins in solution using X-ray photon correlation spectroscopy (XPCS) at nearly diffraction-limited storage rings (DLSRs). We calculate the signal-to-noise ratio (SNR) of XPCS experiments

X Ray Photon Correlation Spectroscopy for the study of polymer dynamics

European Polymer Journal, 2016
X Ray Photon Correlation Spectroscopy, XPCS, is a novel technique developed for the study of slow dynamics in condensed matter. The principle of this technique is based on the time variations of the speckle pattern originated by the scattering of coherent light from a material with spatial inhomogeneities. Although laser photon correlation spectroscopy

Demonstration of 3D photon correlation spectroscopy in the hard X-ray regime [PDF]

Optics Letters, 2022
Three-dimensional photon correlation spectroscopy (3D PCS) is a well-known technique developed to suppress multiple scattering contributions in correlation functions, which are inevitably involved when an optical laser is employed to investigate dynamics in a turbid system.

Nanosecond X-Ray Photon Correlation Spectroscopy on Magnetic Skyrmions [PDF]

Physical Review Letters, 2017
We report an x-ray photon correlation spectroscopy method that exploits the recent development of the two-pulse mode at the Linac Coherent Light Source. By using coherent resonant x-ray magnetic scattering, we studied spontaneous fluctuations on nanosecond time scales in thin films of multilayered Fe/Gd that exhibit ordered stripe and Skyrmion lattice ...

Noise reduction in X-ray photon correlation spectroscopy with convolutional neural networks encoder–decoder models [PDF]

Scientific Reports, 2021
Like other experimental techniques, X-ray photon correlation spectroscopy is subject to various kinds of noise. Random and correlated fluctuations and heterogeneities can be present in a two-time correlation function and obscure the information about the

X-ray photon correlation spectroscopy under flow [PDF]

Journal of Synchrotron Radiation, 2008
X-ray photon correlation spectroscopy was used to probe the diffusive dynamics of colloidal particles in a shear flow. Combining X-ray techniques with microfluidics is an experimental strategy that reduces the risk of x-ray induced beam damage and also allows time-resolved studies of processes taking place in flowcells.

A new experimental setup for combined fast differential scanning calorimetry and X-ray photon correlation spectroscopy [PDF]

Journal of Synchrotron Radiation
Synchrotron-radiation-based techniques are a powerful tool for the investigation of materials. In particular, the availability of highly brilliant sources has opened the possibility to develop techniques sensitive to dynamics at the atomic scale such as ...

Towards ultrafast dynamics with split-pulse X-ray photon correlation spectroscopy at free electron laser sources [PDF]

Nature Communications, 2018
X-ray photon correlation spectroscopy has been mainly used to measure slow dynamics using synchrotron sources. Here the authors demonstrate the split-and- delay pulse set-up to study nanosecond dynamics of gold nanoparticles using XPCS with free electron
