12-BM is a multi-purpose beamline for combined spectroscopy (XAS), Small Angle Scattering (SAXS) and Wide Angle Scattering (WAXS). Quick EXAFS is implemented for transmission experiments with sub 10 second scans. The beamline is designed to provide a versatile platform to cover a wide range of experimental needs; XAS alone or in combination with SAXS and WAXS (we don't run SAXS/WAXS alone only combined with EXAFS).  These are a combination of techniques on the samples under different experimental conditions (heating, cooling, in-situ catalytic reaction conditions). In order to achieve an easily adjustable wavelength between 4.5 and 40 keV, the beamline uses a water-cooled, double-crystal, fixed-exit monochromator with Si(111) and Si(311) crystals. A double mirror system (flat and toroidal) focuses and steers the beam in the experimental station to 0.5 mm x 0.5 mm.
