Grazing-incidence scattering of coherent X-rays from a liquid surface

A. Madsen, T. Seydel, M. Tolan and G. Grübel

Synopsis: The possibility of performing a spatial and temporal analysis of a speckle pattern generated by coherent synchrotron radiation scattered from a liquid surface is demonstrated. Unique surface sensitivity is achieved by applying the X-rays under a grazing angle of incidence. The appearance of the speckle image can be explained by use of geometrical arguments and by the fact that liquid surfaces have very small roughness values.
