Apochromatic X-ray focusing
A team of scientists from the Paul Scherrer Institut, the University of Basel and DESY have demonstrated the first-ever realization of apochromatic X-ray focusing using a tailored combination of a refractive lens and a Fresnel zone plate. This innovative approach enables the correction of the chromatic aberration suffered by both refractive and diffractive lenses over a wide range of X-ray energies. This groundbreaking development in X-ray optics have been just published in the scientific journal Light: Science & Applications.

IEEE Early Career Award 2022
For contributions to the development of detectors for XFELs and specifically for their verification, characterization, and calibration
Dancing molecules
When cycloalkanes are enclosed in a nanometer-sized pore, they adapt their shape - similar to the induced fit concept described in #biochemistry. The molecules do not all behave in the same way and surprisingly start to move when there is a lack of space at 5K.
Thomas Mortelmans receives the Swiss Nanotechnology PhD award
Thomas Mortelmans has been a PhD at the Laboratory for X-ray Nanosciences and Technologies for the last four years. He recently defended his PhD-thesis at the University of Basel entitled: "The development of a nanofluidic particle size sorter and its biomedical sciences" and was awarded the grade of summa cum laude.
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.
Light-Induced Magnetization at the Nanoscale
Targeted manipulations of an atom's magnetic moment are tricky, as the charge currents used for this process are extremely difficult to control . Now, a consortium of collaborators in Germany, Switzerland, Slovenia and Italy reports on a solution to this problem in the cover page article of Physic Review Letters 128, Vol. 15. As it appears, the magnetization of an atomic gas can be altered by high-power lasers using a patterned wave front. The method is promising for studying and manipulating the magnetic properties of matter at the nanoscale.
Hercules School 2022
PSI hosted again the Hercules School in March 2022. We had the pleasure to welcome 20 international PhD students, PostDocs and scientists to demonstrate our state-of-the-art techniques and methodologies at our large scale facilities, the Swiss Light Source (SLS), the Swiss Spallation Neutron Source (SINQ) and our free electron laser SwissFEL.
