Coherent X-ray Scattering Group (CXS)The Coherent X-ray Scattering (CXS) group develops techniques in scanning- and time-resolved SAXS and high-resolution scanning X-ray microscopy at the cSAXS beamline. In collaboration with research groups, within PSI and international universities and research institutes, we apply these techniques to a wide range of problems in the fields of biology, biomedical research and materials science.
Scientific Highlights 2017
For the first time, scientists have made visible the directions of the magnetisation inside a 3D magnetic object. The smallest details in their visualisation were ten thousand times smaller than a millimetre. Among others, the magnetic structure contained one outstanding kind of pattern: magnetic singularities called Bloch points, which up to now were only known in theory.
Researchers at the PSI have made detailed 3-D X-ray images of a commercially available computer chip. In their experiment, they examined a small piece that they had cut out of the chip beforehand. This sample remained undamaged throughout the measurement. It is a major challenge for manufacturers to determine if, in the end, the structure of their chips conforms to the specifications. Thus these results represent one important application of an X-ray tomography method that the PSI researchers have been developing for several years.
