Welcome to the SwissFEL 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.
Scientific Highlights and News
The summer shutdown was used to install more missing hardware. With the new components the Bernina instrument will be already very close to the full design capabilities when the exciting time of user experiments will begin in 2019.
Understanding how and how fast we can drive atoms to create a structural phase transition is of fundamental interest as it directly relates to many processes in nature. Here we show that a photoexcitation can drive a purely structural phase transition before the energy is relaxed in the material that corresponds to a “warmer” equilibrated state.
Data storage devices based on novel materials are expected to make it possible to record information in a smaller space, at higher speed, and with greater energy efficiency than ever before. Movies shot with the X-ray laser show what happens inside potential new storage media, as well as how the processes by which the material switches between two states can be optimised.
