Beam line 2-2 is a bending magnet side-station beam line for x-ray absorption spectroscopy, Quick-EXAFS, and EXAFS measurements of samples with absorption edges in the energy range 4.5 - 37 keV. BL2-2 is equipped with a water-cooled double crystal monochromator, with multiple crystal sets available [Si(111), Si(220)]. Available detectors include ionization chambers, Lytle, 13-element Ge array, and Vortex detectors. Specialized facilities for in-situ catalysis research include gas handling systems and mass flow control. The beam line sees limited use for white beam experiments.
