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.
We have an open position at cSAXS for fluorescence tomography in combination with ptychographic tomography, click here for details.

2018 Richard L. Greene Dissertation AwardClaire Donnelly (LMX group) has been awarded the 2018 Richard L. Greene Dissertation Award in Experimental Condensed Matter or Materials Physics from the American Physical Society, recognizing doctoral thesis research of exceptional quality and importance. This prize is for her dissertation on “Hard X-ray Tomgraphy of Three Dimensional Magnetic Structures.” Claire carried out her dissertation in collaboration with the CXS group and the OMNY project, with experiments at the cSAXS beamline in SLS.
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.
