A transportable surface-science chamber for glancing-angle X-ray diffraction

A transportable surface-science chamber has been designed and constructed to mount on a Huber four-circle diffractometer to perform glancing-angle X-ray diffraction from surfaces or near-surface structures. The chamber permits sputtering and annealing preparation, low-energy electron diffraction (LEED) and Auger electron spectroscopy (AES). To demonstrate the performance of the instrument, results from a rutile TiO₂ (100) 1 X 3 reconstructed surface are reported.
