Beam line 7-2 is a wiggler end station dedicated for x-ray absorption spectroscopy large scale rapid imaging and x-ray absorption spectroscopy (XANES, EXAFS) of biological, material science, and geological samples. A series of polycapillaries and pinholes can provide beam sizes from mm to ~ 35 x 35 microns. The energy range of the beam line optics covers 4.9-16 keV, with detection of fluorescent x-rays as low as Si. BL7-2 is equipped with a 7 element Vortex silicon drift detector and ionization chambers. Sample positions are controlled with submicron accuracy and has a stage motion range of ~1000 mm horizontally and ~300 mm vertically, ideal for obtaining elemental maps of many smaller samples or larger samples.
(After many years of service, the materials science scattering capability was moved from BL7-2 to BL17-2 which is currently in development/commissioning)
