Welcome to the Bernina Group
The Bernina group works on experimental studies of beyond-equilirium ultrafast phenomena in condensed matter. It develops and operates the Bernina Instrument of SwissFEL, which is presently under commissioning and performing first experiments. The group arises from the FEMTO group at the Swiss Light Source.
