The New Highlight in Switzerland's Research Infrastructures
The SwissFEL is based on a novel technology holding exceptional promises for diverse areas of scientific research. Serving our society's modern trends "smaller, faster, more complex", SwissFEL will provide unprecedented insights into structures as small as an atom and into phenomena as fast as the vibrations of molecular bonds. It will also reveal the secrets behind the inner complexity of technologically relevant materials and biochemical structure and interaction.
Read more about SwissFEL in the 'About' Section:
SwissFEL is a compact, high-brilliance, soft and hard X-ray Free Electron Laser (FEL) facility laser composed of two parallel beam lines seeded by a common linear accelerator (LINAC), and a two-bunch photo-injector. For the injector, an innovative dual-photocathode laser scheme has been developed based on state-of-the-art Ytterbium femtosecond laser systems. We just published an overview of the the SwissFEL Photo Cathode Drive Lasers (PCDL) performance, pulse shaping capabilities as well as the versatility of the systems, which allow many different modes of operation of SwissFEL . The full control over the SwissFEL electron bunch properties via the unique architecture of the PCDL will enable in the future the advent of more advanced FEL modes; these modes are, but not restricted to, the generation of single or trains of sub-fs FEL pulses, multi-color FEL and finally the generation of fully coherent X-ray pulses via laser-based seeding.
This experiment performed at SwissFEL shows how fast we can localize electrons out of an electron gas into correlated, well localized states of a material. It is based on a combined ultrafast x-ray absorption and diffraction experiment on an intermetallic system.
