Abstract

Abstract : This work describes the software package CONTIN XPCS for inverse transform analysis of X‐ray photon correlation spectroscopy data. Abstract : X‐ray photon correlation spectroscopy (XPCS) and dynamic light scattering (DLS) reveal materials dynamics using coherent scattering, with XPCS permitting the investigation of dynamics in a more diverse array of materials than DLS. Heterogeneous dynamics occur in many material systems. The authors' recent work has shown how classic tools employed in the DLS analysis of heterogeneous dynamics can be extended to XPCS, revealing additional information that conventional Kohlrausch exponential fitting obscures. The present work describes the software implementation of inverse transform analysis of XPCS data. This software, called CONTIN XPCS, is an extension of traditional CONTIN analysis and accommodates the various dynamics encountered in equilibrium XPCS measurements.
