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 will open position at cSAXS for small-angle scattering tensor tomography in combination with ptychographic tomography. Contact us for details.
Scientific Highlights
Making it easier to differentiate mirror-image molecules
Researchers have shown that mirror-image substances – so-called enantiomers – can be better distinguished using helical X-ray light.
Novel X-ray lens facilitates glimpse into the nanoworld
PSI develops a revolutionary achromatic lens for X-rays.
Revealing invisible defects in fusion reactor armor
In an exciting collaboration, Nick Phillips, a PSI Fellow at the cSAXS beamline, reveals nanoscale lattice distortions created by invisible defects in fusion reactor armor. This work develops the current understanding of how the smallest, but most prevalent defects, generated during neutron irradiation behave. The novel Bragg ptychographic approach published in Nature Communications paves the way for fast, robust, 3D Bragg ptychography.
Ground-breaking technology development recognised
PSI researchers win the international Innovation Award on Synchrotron Radiation for 3D mapping of nanoscopic details in macroscopic specimens, such as bone.
Neurodegenerative disease studied by cryogenic X-ray nanotomography
Hard X-ray cryo-tomography scanning of retina from healthy and inherited blindness specimen paves the way for correlative analysis after imaging at the cSAXS beamline.
Dr. Manuel Guizar-Sicairos is awarded ICO prize
Dr. Manuel Guizar-Sicairos, beamline scientist at the cSAXS beamline, is the 2019 recipient of the International Commission for Optics (ICO) Prize. The distinction was awarded in the EOSAM conference in Rome.
Imaging strain with high resolution
Imaging strain in crystalline materials with high resolution can be a challenging task. Researchers demonstrate an original use of X-ray ptychography for this purpose: ptychographic topography.
How catalysts age
Catalysts used in industry change their material structure over the years. Using a new method, PSI researchers have now studied this on the nanoscale.
Understanding Why Solid-State Batteries Fail
Researchers from the University of Oxford, the Diamond Light Source and the Paul Scherrer Institut have generated strong evidence supporting one of two competing theories regarding the mechanism by which lithium metal dendrites grow through ceramic electrolytes. A process leading to short circuit at high rates of charge. The X-ray phase-contrast imaging capabilities of the TOMCAT beamline of the Swiss light source allowed researchers to visualize and characterize the growth of cracks and dendrites deep within an operating solid-state battery. The results were published in Nature Materials on April 22, 2021.
