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.

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 ...
