Abstract :
The Basic Energy Sciences Synchrotron Radiation Center Collaborative Access Team (BESSRC-CAT) has built a bending magnet beamline for spectroscopy and scattering experiments at the Advanced Photon Source (APS). The windowless beamline uses a water cooled, double crystal, fixed exit monochromator with Si 1 1 1 crystals as the first optical element. The monochromator is capable of operations from 55° to 3° allowing experiments from approximately 2.5–30 keV. A monochromatc double mirror system located in the white-beam enclosure focuses the beam in the experimental station. When the first mirror is removed energies above the mirror cutoff (∼22 keV) can be used. The 12BM-B user station is equipped for scattering (Huber 6-circle diffractometer) and spectroscopy (optical table, ion chambers and solid state detectors) experiments.
