Elastic and Inelastic Scattering

The Elastic and Inelastic Scattering (EISbeamline, associated with the FERMI@Elettra Free Electron Laser (FEL) project, will be dedicated to two different research projects: 

  1. TIME-Resolved spectroscopy of mesoscopic dynamics in condensed matter (TIMER
  2. TIme-Resolved Studies of Matter under EXtreme and Metastable Conditions (TIMEX)

In the first case, the FEL pulses photon energy and brilliance will be used for transient grating formation in the sample with a spatial period (i. e. momentum transfer) at the nanoscale. This would be extremely interesting concerning the physics of disordered systems since it will make accessible the mesoscopic kinematic region that cannot be explored by the use of visible laser based instruments. Transient grating experiments at the nanoscale could also allow sensitive probing of interfaces, extremely thin films, and heat transport and correlations in nanostructured materials. TIMEX will exploit the unique intensity, energy domain and time structure of the FEL to probe metastable and/or excited matter under extreme conditions. In particular, the energy and intensity of theFermi@Elettra FEL beam is suitable for an efficient ultrafast heating of most bulk-like dense samples.
