Beam line 2-2 is a bending magnet end-station beam line dedicated to in-situ X-ray absorption spectroscopy, Quick-EXAFS, and EXAFS measurements of samples with absorption edges of 4.5 - 24 keV. BL2-2 is equipped with a water-cooled double crystal monochromator, with multiple crystal sets available [Si(111), Si(220)]. Available detectors at BL2-2 are currently limited to ionization chambers, Lytle, 13-element Ge array, and Vortex detectors.
