GALAXIES beamline

Research Contents / Beamlines / GALAXIES: IXS - HAXPES

The GALAXIES beamline is dedicated to inelastic x-ray scattering (IXS) and hard x-ray photoemission (HAXPES). These spectroscopic techniques are powerful probes to characterize the electronic properties of materials. The beamline is optimized to operate in the 2.3 et 12 keV energy range with high resolution and micro beam.

Hard x rays induce a MUST ultrafast dissociation phenomenon.

Interaction of light with matter is multifarious. Light can be absorbed, emitted, reflected, scattered. It can warm and cool, destroy or heal. Light, or electromagnetic radiation, of various specific characteristics, is often used in research to get insights into the laws of nature, e.g. properties of matter, its structure, formation or degradation. The energy carried by the absorbed light may lead to matter ionization or its transfer to unstable transient excited states, which would then relax, releasing the excess energy (all at once or by portions in several steps) in many forms, e. g. emission of photons and/or electrons, which is often accompanied by structural deformations, such as changes in bond lengths, twisting and rotation of bond angles, isomerization or even bond breakages.
