Short pulsed analysing radiation of high intensity enables to study evolution of chemical, biological processes, fast structural transformations. Recently commissioned high brilliance photon sources, synchrotrons, optical and x-ray lasers produce unprecedentedly high energy density on the target at a high repetition rate never seen before – opening fields of exciting research of reactions that have been far too rapid to be captured by former methods. The wavelength of the X-rays falls into the range of a few hundreds of to a few nanometers, enabling measurements on the atomic length scale. Hungarian researchers have successfully contributed to the construction of the Extreme Light Source (ELI) and the European X-ray Free Electron Laser (EuXFEL) EU infrastructures and have gained regular access to these state-of-the-art analytic facilities.
With the help of the distinguished presenters of the next BNC webinars we look deeper into this field to learn about the principles, present applications and future promises of the advanced pulsed photon sources.

Abstract:
Modern pulsed X-ray sources offer unprecedented short and intense X-ray probes to study physical and chemical phenomena in their intrinsic time domains or at extreme conditions. The new era of time resolved investigations opened by the novel X-ray free electron lasers, like the European XFEL in Schenefeld, and ultra strong laser pulses, like the ELI initiative, enables to unravel the nature of femtosecond scale photochemical reactions, spin-state switching, ultrafast rearrangement of photoactive biochemical entities, temporal fluctuations of skyrmions, to name a few recent successful experiment. This review aims to give an introductory overview of recent and prospective applications of these new X-ray sources.
