In situ, time-resolved techniques provide valuable insights into the complex interplay of kinetic and equilibrium mechanisms active during materials synthesis and subsequent processing.  X-ray based versions are particularly well suited to penetrate chamber walls and complex reactive environments. With the brilliance and coherency of the x-ray beams at hard x-ray synchrotrons, such as at the Advanced Photon Source (APS) at Argonne National Lab, it is possible to exploit the sensitivity of surface scattering techniques used in-situ, to quantify atomic to microscale structure and its evolution within thin epitaxial films under complex environments.
