The unprecedented brilliance and narrow pulse duration of the Linac Coherence Light Source provides a unique opportunity to observe dynamical changes of large groups of atoms in condensed matter systems over a wide range of time scales using Coherent X-ray Scattering (CXS) in general and X-ray Photon Correlation Spectroscopy (XPCS) in particular. The X-ray Correlation Spectroscopy (XCS) instrument at the LCLS allows the study of equilibrium- and non-equilibrium dynamics in disordered or modulated materials.
The XCS instrument is located in Hutch 4 of the Far Experimental Hall of LCLS. The XCS instrument is located about 420 m away from the source. Characteristic timescales ranging from 10 milliseconds to thousands of seconds can be explored using a sequential mode of operation. Ultrafast timescales ranging from 100 femtosecond to several nanoseconds can be probed using a novel “Split-and-Delay” mode of operation.
