THE STATION IS PRESENTLY CLOSED - March 2017
Surface diffraction is a unique tool for determining the detailed atomic structure of crystalline surfaces. The SD station in the last experimental hutch of the Materials Science beamline contains a large diffractometer, of the "2+3" geometry of E. Vlieg, for in-situ surface diffraction experiments with removable, user-supplied sample environment chambers.
Three chamber geometries are possible: a "baby chamber" with vertical sample, weighing up to 50 kg, a "cryostat chamber" with horizontal sample, weighing up to 200 kg, and a "heavy UHV chamber" with vertical sample mounted on a vacuum feedthrough, weighing up to 500 kg. The standard detector system is the 2-dimensional solid-state PILATUS II detector.
