Konferensbidrag (refereegranskat)abstract
- We are developing a tabletop apparatus for time-resolved X-ray absorption spectroscopy. Short X-ray pulses are generated by focusing a pulsed 800 nm laser onto a water jet target. X-rays that pass through a sample of interest are detected using energy-resolving superconducting microcalorimeter detectors. We have successfully observed EXAFS features from iron tris(bipyridine) in a water solution. We discuss details of the microcalorimeter spectra and describe the steps that remain before the intrinsic sub-picosecond sensitivity of the apparatus can be realized.
