Using ultrashort X-ray pulses for multidisciplinary investigations

X-rays produced by new free-electron lasers promise to push our gaze deeper into inorganic and living matter and to reveal structures and dynamics at nanoscale.

X-rays are one of the key probes of atomic structure, electronic and magnetic properties of condensed matter. The synchrotron light sources developed from accelerator physics provide unique tools for the study of nanostructures both in inorganic and living matter. The all new pulsed sources, based on the free electron lasing phenomenon, make possible to design novel experiments where, for example, the structure of a single nanoparticle (cluster, protein, virus, ...) may be resolved from a single pulse exposure, as well as experiments where the dynamical behaviour of matter during synthesis or during magnetization can be followed in real time on the relevant time scale. Some ideas and perspectives of new experiments are presented (photo credit: Janos Hajdu, Uppsala University).
