Description

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.

Equipment and resources

Laser system and parameters: Pump – 1 kHz repetition rate, 800nm, 400nm, or OPA (TOPAS, Light Conversion) output, probe – detector limited – 2-9 keV X-rays, <1ps
