N2 - The UNICAT collaboration at the APS has constructed an insertion device beamline facility to support fundamental research in advanced materials and condensed matter physics. The primary research techniques used by UNICAT members include structural crystallography, diffuse x-ray scattering, magnetic x-ray scattering, ultra-small-angle x-ray scattering, micro-beam scattering, inelastic x-ray scattering and spectroscopy, surface and interface scattering, coherent x-ray diffraction, and time-resolved techniques. To support these advanced x-ray techniques for a diverse scientific community, we chose a liquid-nitrogen cooled Si (111) double crystal monochromator, and a pair of coated, striped mirrors. Important parameters considered in the design of the beamline are x-ray flux, energy range and bandwidth, source demagnification, and harmonic contamination. The APS type A undulator is used to produce high-brilliance X-rays between 4 and 40 KeV. We achieve sagittal focusing by dynamically bending the monochromator second crystal, and meridional focusing by cylindrically bending one of the flat mirrors. The resulting x-ray beam delivered to the experimental stations can be focused, unfocused, or collimated. The overall design of this beamline layout and the major beamline components are described, and its performance is discussed with respect to impact on the scientific programs proposed for the facility.
