Description
Electron scattering instrumentation has evolved into a powerful tool for revealing the atomic structure enabling the visualization of the dynamic evolution of matter in real time, providing crucial information on phase transition and chemical reaction dynamics, among other phenomena. Ultrafast electron pulses have facilitated this scientific endeavor, thanks to rapid advances in both ultrafast laser and particle accelerator technologies. In this talk I will discuss the physics of high brightness electron sources for ultrafast electron diffraction (UED) and review the recent technical developments which have tremendously improved the spatial and temporal resolution in the experiments. I will also include a discussion of the opportunities to further push the state-of-the-art in the technique and continue to improve its performances.
