Welcome to the Institute for Photon Science and Synchrotron Radiation

The IPS conducts research for and with novel synchrotron analytics and diagnostics (X-ray imaging, spectroscopy, and scattering). Particular focus is placed on in situ, operando, and in vivo techniques for the characterization of technological and biological processes, with emphasis on materials and processes for energy conversion and transport technologies, nano- and information materials, and imaging in the life sciences.

Stress evolution during formation of metal/silicon interfaces


In collaboration with the University of Poitiers, we have developed a unique experimental approach combining real-time curvature measurements and synchrotron x-ray reflectivity and diffraction in order to identify the microstructural origins of the stress evolution during sputter deposition of thin films[1].

First high-speed hard X-ray microscopic movies at a free-electron laser


At the European X-ray Free-Electron Laser (EuXFEL) in Schenefeld, Germany a research team have demonstrated for the first time the use of Megahertz (MHz) high-speed X-ray laser microscopy to image the rapid microscopic processes induced by laser heating of water-filled capillaries. Their experiments show how processes taking place at speeds up to a few kilometers per second can be studied, paving the way for 3D microscopic movies of similarly fast phenomena, with important potential industrial applications.

Understanding atomic vibrations at interfaces


Propagating lattice vibrations, known as phonons, are responsible for the transmission of sound and heat in solids. In addition, by coupling to electrons and magnons they influence remarkably many materials properties. Due to the broken translational symmetry, the atomic vibrations at interfaces are drastically modified compared to their bulk counterparts.
