Strategies to perform and optimize x-ray photon correlation spectroscopy experiments
Abstract X-ray photon correlation spectroscopy (XPCS) is an emerging technique to characterize nanoscale dynamics in-situ. This is a powerful yet challenging technique, requiring many experimental conditions such as high coherence, high stability, and high coherent flux. These conditions are not directly available at most existing beamlines, such that XPCS can only be performed at a few beamlines with coherent x-ray beams. In this work, we performed a series of XPCS experiments at a scattering beamline not dedicated for coherent applications. By systematically study the effects of coherence, stability, and coherent flux, we demonstrate practical means to perform and optimize XPCS experiments. We hope this work can help to apply this emerging technique at more beamlines, in particular at existing beamlines with non-coherent x-ray beams.
