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.

Resolving molecular diffusion and aggregation of antibody proteins with megahertz X-ray free-electron laser pulses

Nature Communications, 2022
The European X-ray FreeElectron Laser Facility generates ultrashort hard X-ray pulses with megahertz repetition rate. Here, the authors probe the dynamics of dense antibody protein (Ig-PEG) solutions using megahertz X-ray photon correlation spectroscopy ...

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.

Indirectly illuminated X-ray area detector for X-ray photon correlation spectroscopy [PDF]

Journal of Synchrotron Radiation, 2010
An indirectly illuminated X-ray area detector is employed for X-ray photon correlation spectroscopy (XPCS). The detector consists of a phosphor screen, an image intensifier (microchannel plate), a coupling lens and either a CCD or CMOS image sensor. By changing the gain of the image intensifier, both photon-counting and integrating measurements can be ...

X-ray free-electron laser heating of water at picosecond time scale

Physical Review Research, 2022
Split-pulse x-ray photon correlation spectroscopy using x-ray free-electron laser is a promising tool to probe atomic dynamics in liquid and soft-matter in picosecond time scale, which has been accessible only by spectroscopy.

Single and multi-pulse based X-ray photon correlation spectroscopy

Optics Express, 2023
The ability of pulsed nature of synchrotron radiation opens up the possibility of studying microsecond dynamics in complex materials via speckle-based techniques. Here, we present the study of measuring the dynamics of a colloidal system by combining single and multiple X-ray pulses of a storage ring.
