On January 30th, 2020, the WHO declared the recent outbreak of coronavirus disease 2019 (COVID-19), a public health emergency of international concern. It declared that there is an urgent need to improve our understanding of the newly identified virus and its possible future evolution as well as to contain the spread; to develop precise diagnostics and treatment, and to improve the public health response and patient care.
The COVID priority access call continues and is still open in 2022.
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.
The path to experiments that are unique in the world is now open.
Light is essential for life, and for researchers it is also a wonderful tool to better understand the structure of materials.
Another site for the Swiss Data Science Center will be established at PSI. This expansion is expected to give a further boost to the data sciences in Switzerland.
A new PSI method allows quantum-physical research on materials with the aid of X-ray lasers.
