ID03

Synopsis

The beamline is dedicated to the in-situ studies of the structure and morphology of surfaces. It hosts two diffractometers, one for UHV studies and one that can host different user-specific apparatuses. Real-time experiments are possible, giving the possibility of studying growth processes or reaction at surfaces (as heterogenous catalysis).
