European Synchrotron Radiation Facility
ID24 - EDXAS
Currently not operational

ID24, the Energy Dispersive X-ray Absorption Spectroscopy (EDXAS) beamline hosts two independent EDXAS branches, which use beam on a time-shared basis.

The beamline is primarily used to investigate the electronic and local structure in crystalline, amorphous and liquid matter in a variety of thermodynamical and reaction conditions. Experiments fall into two main categories:

  • Studies of matter at extreme conditions of pressure, temperature and magnetic field
  • Time resolved studies of dynamical processes

The research on ID24 covers different scientific domains, including solid state physics, materials science, geosciences, environmental science, solution chemistry, heterogeneous and homogeneous catalysis.
