Specifications include, but are not limited to: The University of Wisconsin-Madison, Department of Chemical and Biological Engineering is seeking bids for a small and wide-angle X-Ray scattering system capable of achieving structural information with length scales of 2-200 nm for solid, liquid, gel and powder samples. The equipment will be housed in the Soft Matter Characterization Laboratory in Engineering Hall and will be used for research and teaching purposes. Large Q-range of measurement from Qmin = 0.009 nm-1 up to Qmax ≥ 49 nm-1 with continuous Q-range of measurement and automated change of measuring settings (flux, X-ray beam size on sample and sample to detector distance) in transmission X-ray scattering measurements . Capability to analyze anisotropic samples with large Q-range of measurement from Qmin = 0.009 nm-1 up to Qmax ≥ 43 nm-1 with 360° azimuth angle . GISAXS/GIWAXS capability with motorized change of sample to detector distance to achieve a continuous Q-range of measurement up to Qmax=40 nm-1 (in plane and out of plane scattering measurement) . High useful flux: capability to perform X-ray scattering measurements with a flux at sample ≥ 100 Mph/s with a max total flux of the source on sample is ≥ 500 Mph/s . Beamstop-free data acquisition for improved data treatment to allow accurate absolute intensity scaling through measurement of sample transmission during scattering measurement from direct beam measurements. . Stage capable of holding multiple samples for liquids, solids or powders with variable temperature capabilities from -150°C to + 350°C. . Point microfocus sealed tube-Copper anode with power of 30 Watts (source size ≤35µm in both directions according to DIN EN 12543-5) coupled to 2D single reflection multilayer for 2D beam conditioning and good Kα filtering.
