Beam line 2-3 is a bending magnet side station dedicated to x-ray imaging and micro x-ray absorption spectroscopy (edge, EXAFS) as well as micro diffraction of biological, material, and geological samples.  A Kirkpatrick-Baez mirrors system is used to achieve microfocus with a beam size of ~ 2 x 2 microns. The energy range of the beam line optics covers 4.9-23 keV, with detection of fluorescent x-rays as low as Si. BL2-3 is equipped with a Vortex silicon drift detector and ionization chambers.  Sample positions are controlled with submicron accuracy by two different sample stages depending on the experiment.  BL2-3 is ideal for obtaining elemental maps of small samples (about 10 microns to 25 mm) as well as performing spectroscopy on selected points in the sample (~ 2 x 2 microns).
