Summary, in English

We report on the development and first experiments at a new X-ray absorption spectroscopy (XAS) endstation at the FemtoMAX beamline of the MAX IV Laboratory. Femtosecond time-resolved XAS measurements on solvated photoexcited molecular systems were performed with pulse-width-limited temporal resolution. The results demonstrate nearly shot-noise-limited signal quality, highlighting the capability of this endstation to extract detailed electronic and geometric structural information.
