Beamline 12-BM-B: Multipurpose X-ray Absorption and Scattering
X-ray Science Division, APS
Materials Science, Polymer Science, Chemistry, Environmental Science, Physics, Catalysis
Description
12-BM is a X-ray Absorption Spectroscopy (XAS) beamline with simultaneous SAXS/WAXS capability. The beamline uses a water-cooled, double-crystal, fixed-exit monochromator with Si(111)/Si(311) crystals capable of operations between 4.5 and 40 keV. A double mirror system (flat plus toroidal) with a cutoff energy of 40 keV focuses the beam in the experimental station to 0.5 mm x 0.5 mm. Supported techniques include EXAFS, XANES and combined XAS - SAXS/WAXS. The end station is equipped with a Vortex-ME7 with Xspress3 electronics for spectroscopy, MX225 (Rayonix) and MerlinX (Quantum Detectors) for SAXS/WAXS.
