Quick-Scanning QEXAFS in grazing incidence: Surface science in sub-seconds

Quick scanning X-ray absorption spectroscopy was combined with the grazing incidence geometry for the time resolved in situ investigation of surfaces and thin films. The results demonstrate that a time resolution of about 50 ms for a single spectrum is feasible using a dedicated monochromator. In-situ investigations performed during the sputter deposition of thin gold films demonstrate the capabilities of this new approach.
