Beamline 12-BM-B: Sector 12 - Bending Magnet Beamline

Description

12-BM is a bending magnet beamline dedicated to spectroscopy scattering experiments. The beamline uses a water-cooled, double-crystal, fixed-exit monochromator with Si(111) crystals capable of operations between 4.5 and 30 keV. A double mirror system (flat plus torroidal) with a cutoff energy of 23 keV focuses the beam in the experimental station to 0.8 mm x 1 mm. Unfocused beam can be used for higher energies. The end station is equipped with a 13-element Ge detector and 6-circle Huber diffractometer. Supported techniques include XAFS, XANES, SAXS,scattering and diffraction.
