*The split and delay capability is still under commissioning for the XCS instrument.
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 420m 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.
