Title: Research with free-electron lasers: new horizons for ultrafast x-ray sciences
Speaker: Christoph Bostedt, SLAC
Abstract: Free-electron lasers deliver extremely intense, coherent x-ray flashes with femtosecond pulse length, opening the door for imaging single nanoscale objects in a single shot and ultrafast spectroscopy of core-level electrons. After an introduction to free-electron lasers, I will present selected science examples enabled by these sources. Imaging of individual superfluid helium nanodroplets allows the unambiguous identification of quantum vortices. Ultrafast scattering of small highly excited nanoplasmas carries information about their transient electronic states. The combination of optical with x-ray lasers allows the investigation of dynamically evolving systems with femtosecond time and nanometer spatial resolution. I will end my talk with an outlook on where I see the field heading in the next years and what exciting opportunities can be envisioned.
