high-flux beamline for electron and soft & hard x-ray spectroscopy of materials for energy applications

X-SPEC is a high-flux beamline for electron and soft & hard x-ray spectroscopy of materials relevant for energy applications, covering a wide energy range from 70 eV to 15 keV. In collaboration with our partners at KIT’s Institute for Chemical Technology and Polymer Chemistry (ITCP), X-SPEC operates two experimental stations which offer x-ray absorption spectroscopy (XAS), extended x-ray absorption fine structure (EXAFS), photoelectron spectroscopy with soft and hard x-rays (PES/HAXPES), as well as x-ray emission spectroscopy (XES) and resonant inelastic x-ray scattering (RIXS).

At the first experimental station, samples can be investigated under ultra-high vacuum (UHV) conditions, while the second experimental station is optimized for in situ and operando studies.

The beamline is currently in a commissioning/early operation stage.
