XPCS
X-ray Photon Correlation Spectroscopy (XPCS) is a technique that exploits a coherent x-ray synchrotron beam to measure the dynamics of a sample. By recording how coherent speckle fluctuations in time, one can measure a time correlation function, and thus measure the timescale processes of interest (diffusion, relaxation, reorganization, etc.).
