Abstract
X-ray Photon Correlation Spectroscopy (XPCS) is a powerful technique that exploits the spatial and temporal coherence of synchrotron radiation to probe nanoscale dynamics in soft and disordered systems. By analyzing temporal fluctuations in coherent scattering patterns, XPCS provides access to equilibrium and nonequilibrium dynamics over a wide range of length and time scales.
In this talk, I will introduce the basic principles of XPCS and its implementation at synchrotron storage rings, with an experiment from the P10 beamline at PETRA III using complex polymer systems. Furthermore, I will discuss how XPCS complements conventional structural probes to deepen our understanding of dynamic processes in complex polymer materials, and present future perspectives for coherent scattering research at the upcoming Korean 4th Generation Storage Ring, where enhanced coherence and beam stability will enable next generation SAXS and XPCS studies.
