Surface X-ray scattering system at the SRRC.
A UHV surface X-ray scattering system has been constructed at the SRRC, providing users with a state-of-the-art system for performing X-ray scattering studies of two-dimensional crystallography, in situ growth mechanisms as well as phase transitions of surfaces and interfaces. A study of the phase transition of the Si(001) reconstructed surface was conducted to commission both the scattering system and the SRRC X-ray beamline. The detailed design and performance of the SRRC surface X-ray scattering system together with the results of the Si(001) study are presented.
