GENERAL DESCRIPTION:	BL13-2 has stations designed for surface and solid state experiments. The SSE station has an electron spectrometer (SES-R3000, VG-Scienta) for photoemission spectroscopy and Auger electron yield X-ray absorption spectroscopy, and a Ni coated elliptical grating spectrometer for C 1s, N 1s and O 1s x-ray emission spectroscopy. A horizontally mounted manipulator is provided for experiments with a minimum sample temperature of about 40 K. The manipulator transfers samples between the preparation chamber and the main chamber. Sputtering, evaporation and gas dosing facilities are available in the preparation chamber. A load-lock system for sample introduction can be mounted with limited sample manipulation and preparation capabilities. The APPES station, developed for XPS measurement under a few tenth of atmospheric pressure, is in commissioning in FY11. See video on the role of aluminum foil in vacuum chamber 'bakeouts.'
