Abstract

Ultra-small-angle X-ray scattering—X-ray photon correlation spectroscopy (USAXS-XPCS) is a novel measurement technique for the study of equilibrium and slow nonequilibrium dynamics in disordered materials. This technique fills an existing gap between the accessible scattering vector ranges of dynamic light scattering and X-ray photon correlation spectroscopy. It also overcomes the limits of visible light scattering techniques imposed by multiple scattering and is suitable to study optically opaque materials containing near-micrometer sized structures. In this article we present an overview of the important technical aspects of USAXS-XPCS and offer a few examples as well as future outlooks to illustrate the capability of USAXS-XPCS for monitoring equilibrium and nonequilibrium dynamics.
