Laboratory for Applications of Synchrotron Radiation (LAS)

Welcome to the Laboratory for Applications of Synchrotron Radiation (LAS) at KIT

The Laboratory for Applications of Synchrotron Radiation (LAS) (German: Laboratorium für Applikationen der Synchrotronstrahlung) develops technologies and methods for the investigation of structural and functional relationships in biological systems, condensed matter and functional materials, using synchrotron radiation and novel accelerators.

Key areas of research and development activities at LAS

Our research projects involve active collaboration partners  from Germany, Europe and beyond.

LAS promotes and pursues the education and training of students, doctoral researcher, and young scientists by offering lecture courses, tutorials, practicals and thesis projects in areas such as accelerator physics, materials research, and synchrotron technology.

The laboratory LAS is based at the Campus South of the Karlsruhe Institute of Technology (KIT), but is involved in the development of accelerators such as FLUTE and KARA, use of synchrotron radiation at the KIT synchrotron and light source, the Test Facility and Synchrotron Radiation Source at the Campus North. Members of LAS are also major users of other synchrotron radiation sources world-wide such as ESRF, DESY, ALS, and APS.

A New Crystal Experience

A new, very generally applicable imaging approach provides not only three-dimensional information about complex arrangements of dislocations inside monocrystals, but also allows us to investigate precisely the behavior and role of all the individual defects during plastic deformation process. Based on this methodology, we are able to shed new light on the mechanisms involved in the thermally induced plastic deformation of silicon wafers, the understanding and prediction of which is crucial for semiconductor processing in the context of present and future scientific and industrial applications.


Dynamics of laser-excited gold nanorods

Time-resolved X-ray scattering with 100 picosecond time resolution shows laser-induced dynamics of gold nanorods, which are an attractive tool for biophotonics.

Phonon nanoengineering: Vibrations of nanoislands dissipate heat more effectively

Europium silicide has for some time attracted the attention of scientists. Recognized as being promising for electronics and spintronics, this material has recently been submitted by a team of physicists from Poland, Germany and France to comprehensive studies of the vibrations of its crystal lattice.
