      Beamline Description
      CMS provides instrumentation for simultaneous small- and wide-angle x-ray scattering (SAXS, WAXS) as well as scattering in grazing incidence geometry (GISAXS, GIWAXS), giving access to complementary information at multiple length scales ranging from Angstroms to submicrons. In addition, the moderate microfocusing capability enables scanning microbeam characterization of heterogeneous materials at resolutions of tens of microns. The beamline will also develop capabilities for automation-aided intelligent exploration of vast parameter spaces.

      Optical System
      Double multilayer monochromator. Primary toroidal focusing mirror. Secondary KB mirrors.

      Experimental Apparatus
      Area detectors: Pilatus 300k for SAXS (to be upgraded to Pilatus 2M in summer 2017); Photonic Sciences in-vacuum CCD for WAXS. Ion chambers, scintillatior, diamond diode, and photo diodes for beam intensity monitoring. Computer-controlled sample position, tilt, and rotation stages. Temperature-controlled sample holders for array of capillaries and thin films. Option for in-vacuum sample environment. On-axis and off-axis sample viewing.

      Computer System Hardware & Software
      Beamline components are controlled by EPICS. The user interface is through CSS-Studio and Python clients. The user views the experimental system (sample and the surrounding environment) through CCD-coupled optical microscopes using Prosilica cameras. Linux Debian running IOCs. Dedicated Linux and Windows computers for area detectors.
