DESCRIPTION:Time-resolved electron imaging\, diffraction and spectroscopy a
 re exceptional laboratory-based tools to trace non-equilibrium dynamics in
  materials with a sensitivity to structural\, electronic and electromagnet
 ic degrees of freedom. The capabilities of these approaches are largely go
 verned by the quality of the beam of electrons used.This talk will discuss
  recent advances made by employing high-coherence ultrashort electron puls
 es from nanoscale field emitters\, which substantially enhance the achieva
 ble image resolution in both real and reciprocal space. Two complementary 
 developments with ultimate surface sensitivity and spatial resolution\, re
 spectively\, will be presented\, namely Ultrafast Low-Energy Electron Diff
 raction (ULEED) and Ultrafast Transmission Electron Microscopy (UTEM). Sev
 eral recent examples of applying these methods to the observation of phase
 -ordering kinetics\, the excitation of strongly-coupled fluctuation modes 
 and the control of metastable states will be given.\nVortragende(r): Claus
