The new Swiss X-ray Free Electron Laser (SwissFEL) facility at PSI delivers fsec photon pulses of coherent x-rays in the wavelength range 0.1 to 7 nm, with extremely high peak brightness. The Aramis SwissFEL branch, dedicated for hard X-ray, is in user operation with two end-stations since 2018. The Alvraend-station is focused on using time resolved x-ray spectroscopy (XAS/XES) to investigate femtosecond chemical processes and time-resolved x-ray diffraction for serial femtosecond crystallography (SFX) experiments on proteins. The Bernina end-station is designed for femtosecond time-resolved pump-probe hard x-ray diffraction and scattering experiments in condensed matter systems.
Athos, the second SwissFEL branch for soft x-ray, has its first FEL light in December 2019 and the user program will start in 2021 with two additional end-stations.Athos design includes a novel layout (CHIC) of alternating magnetic chicanes and short undulator segments. Together with the APPLE X architecture of undulators, the Athos branch can be operated in different modes producing FEL beams with unique characteristics ranging from attosecond pulse length, multi color beam to high-power modes. The Athos Maloja end-station will be dedicated to atomic, molecular, and optical physics (AMO), and the Furka end-station is designed for time resolved resonant inelastic and elastic x-ray scattering on condensed matter and quatum material including non-linear x-ray Science.
In the talk the basic and unique principles of the SwissFEL will be presented, experiences from the first commissioning and results of some of the first experiments will be shown. Further, the future plans of SwissFEL will be highlighted.
