Introduction of Beamline
BL38B1
BL38B1 is a beamline that specializes in routine diffraction experiments using crystals with sufficient diffracting quality. It is also equipped with a sample changer robot, SPACE, for automatic measurements.

  • Measurement of standard size (> 50 μm) crystals and standard unit-cell(< 250 A) crystals.
  • MAD and SAD measurement using wide-range X-ray energy (6.5~17.5 keV).
  • Microspectroscope
  • CMOS ditector: a shutterless continuous rotation method
  • Mail-in Protein Crystallography Data Collection Servise

BL41XU
BL41XU is a public beamline for macromolecular crystallography. This beamline is suitable for the following analyses because of the high-flux and high-parallel beam generated by the undulator.

  • Measurement of small-size (~10 μm) crystals and large-unit-cell (>600 A) crystals.
  • MAD and SAD measurement using wide-range X-ray energy (6.5~35 keV).
  • Ultra-high resolution (>0.8 A) structural analysis using >20 keV X-ray energy.

Two types of cryostream coolers, nitrogen gas (~100 K) and helium gas (~30 K), are installed on the diffractmator for experiments under cryogenic conditions.
