Scientific Highlights

Delay vs. photon energy map of an ammonium iron(III) oxalate solution. The large bandwidth emission covers the full XANES range, making time-consuming monochromator scans obsolete.

Efficient transient X-ray absorption spectroscopy

By combining the unique large bandwidth emission mode of SwissFEL’s ARAMIS undulator and diffractive X-ray optics made of diamond, we have demonstrated a new method for time-resolved X-ray absorption near edge structure (XANES) spectroscopy that enables faster data acquisition and requires smaller sample quantities for high-quality data.

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.

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.

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.

Diamond gratings for XFEL amplitude-splitting delay line

A split-and-delay line for XFEL pulses has been built and successfully tested by a team of researchers at the Linac Coherent Light Source. Key X-ray optical elements are two diamond diffraction gratings made at the Paul Scherrer Institut that are used to split and later recombine the intense ultrashort X-ray laser pulses for time-resolved measurements.
