ABSTRACT

  The main research field of BL40B2 is small angle x-ray scattering from biological non-crystalline materials. BL40B2, which is named Structural Biology II, was planned for carrying out the structural analysis of biological molecular, polymers and other materials. For this purpose, this was designed to use the monochromatic X-ray and arranged to be suitable for getting static scattering or diffraction images with high accuracy and high spatial resolution.  BL40B2 was commissioned from October 1999 to December 1999.  Since January 2000, the beamline has been open for public users and used for many studies on the structural analysis of many kinds of proteins, polymers and so on.

AREA OF RESEARCH

• Noncrystalline small and wide angle X-ray scattering

KEYWORDS

• Scientific field
  Small angle X-ray (solution) scattering (SAXS), Structural biology, Protein, Polymer, Fiber, Diffraction
• Equipment
  Pilatus3S 2M, Eiger2 S 500K, Pilatus 100K, Imaging plate(300 mm x 300 mm), 4-inch x-ray Imaging intensifier(100-mm diameter), Pixel array detector, X-ray flatpanel sensor

SOURCE AND OPTICS

  The light source is a bending magnet that has its magnetic field at 0.679 T and shows critical energy of 28.9 keV. The generated white X-rays are monochromatized using a fixed-exit double crystal monochromator and focused by a 1-m-long rhodium-coated bent-cylinder mirror. The glancing angle of 3.2 mrad is adjusted for the optimum focusing at the detector position. The photon flux is 10¹¹ at 12 keV. The energy resolution (ΔE/E) is in the order of 10^-4.
