The small angle x-ray scattering beamline at the J. Bennett Johnston, Sr. Center for Advanced Microstructures & Devices is located on bending magnet port 6A of the CAMD storage ring. The LNLS double crystal monochromator allows photon energies to be selected from roughly 3 to 14 keV.  Beam size on the sample and parasitic scattering are controlled by three interchangeable pinholes, with a current diameter of 200, 400, and 800 μm.  The SAXS sample chamber incorporates computer controlled 2D sample translation stages for alignment and sample change.  Sample dynamics can be studied with the shear cell and hot stage.  The scattering pattern is imaged with a Gabriel style multiwire gas detector with a 200 mm active diameter and a resolution of 200-250 μm FWHM in a 1024 x 1024 array.  A segmented flight path allows q‑ranges from .0015 to .44 Å^-1 to be studied.
