ABSTRACT

  Most of proteins substantially important in biological research have difficulties in growing single crystals of sufficient size. Demands for synchrotron radiation facilities for providing innovative technologies to achieve protein crystallography with micro-sized crystals are increasing more and more. At SPring-8, a new protein micro-crystallography beamline BL32XU is under construction for Targeted Proteins Research Program promoted by MEXT of Japan. The beamline is designed to provide the stabilized and brilliant micro-beam to collect high-quality data from micro-crystals. The highly brilliant micro-beam will be a powerful tool to obtain diffraction data with high signal-to-noise ratio even from weakly diffracting small crystals, by enhancing diffraction signal, and also by reducing background scattering around sample. User operation is planned to start in April 2010.

AREA OF RESEARCH

  • Structural biology
  • X-ray crystallography
  • Micro crystallography

Keywords

  • Specification
    - Micro focus
    - High flux density
  • Equipments
    - Focusing mirrors fabricated with EEM technique
    - Hybrid photon counting detector

SOURCE AND OPTICS

  The beamline consists of a hybrid in-vacuum undulator, a liquid-nitrogen cooled double crystal monochromator, and K-B focusing mirrors with large reduction ratio. High precision monochromator has been specially designed based on the SPring-8 standard double crystal monochromator. The focusing mirror surfaces are fabricated in atomic level accuracy with Elastic Emission Machinery (EEM) technique. The beam size is variable with a high-precision slit as virtual light source according to designed experiments. We confirmed that the beam size of 1 x 1 μm2 with photon flux density of 6 x 1010 phtons/sec/μm2 was achieved at sample position.

EXPERIMENTAL STATIONS

The ultra-high precision diffractometer is being developed now.
