This thesis presents the development and implementation of a novel experimental setup
for time-resolved soft X-ray absorption spectroscopy on liquid samples at SwissFEL. The
setup allows the investigation of important absorption edges, such as the nitrogen ...
The ability to freely control the polarization of X-rays enables measurement techniques relying on circular or linear dichroism, which have become indispensable tools for characterizing the properties of chiral molecules or magnetic structures. Therefore, ...
The recent demonstration of isolated attosecond pulses from an X-ray free-electron laser (XFEL) opens the possibility for probing ultrafast electron dynamics at X-ray wavelengths. An established experimental method for probing ultrafast dynamics is X-ray t ...
We demonstrate the generation of widely tunable two-color x-ray free-electron laser (FEL) pulses at Swiss-FEL. In a split-undulator configuration, each color is produced in a different undulator section, and a chicane between the two sections allows for a ...
