Time-resolved XPCS analysis across broad time-scales using multi-tau two-time correlations [PDF]

Journal of Synchrotron Radiation
We present a multi-tau two-time correlation (MT-2TC) analysis for X-ray photon correlation spectroscopy that enables efficient analysis of large-scale, high-frame-rate datasets collected at modern synchrotron beamlines. The method combines the advantages

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

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 ...

Dynamics of soft nanoparticle suspensions at hard X-ray FEL sources below the radiation-damage threshold

IUCrJ, 2018
The application of X-ray photon correlation spectroscopy (XPCS) at free-electron laser (FEL) facilities enables, for the first time, the study of dynamics on a (sub-)nanometre scale in an unreached time range between femtoseconds and seconds.

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

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
