Transient X-ray spectroscopy - Millenia lab @Chemical Physics






    Transient x-ray absorption and emission spectroscopy with sub picosecond temporal resolution. Laser generated broadband x-rays are used to probe transient states in matter. The x-rays are generated by the interaction of a high-power laser beam with a water jet, resulting in x-rays with <15 keV. The x-rays are handled in a compact setup and can be re-focused with a poly-capillary lens. The x-radiation is detected with a cryogenic microcalorimetric array that can detect 300 – 9000 eV photons. Typical measurements are pump-probe studies of light-induced charge dynamics in metalorganic compounds or nanostructures.
