Super Photon ring-8 GeV

SPACE Automounter

BL44B2 is the Materials Science beamline using total scattering, which is based on measurements of both Bragg and diffuse scattering. Unlike powder diffraction beamlines and PDF beamlines, total scattering beamlines require a fine-Q (the magnitude of scattering vector) step in a wide range of Q. This beamline yields total scattering data with a step of 10-3 Å-1 in a range of 30 Å-1, which definitely have a signal-noise ratio of 105 and over. Thus, the beamline allows crystal- and local-structure analysis of a variety of materials, such as crystalline, amorphous, nano, and porous materials.1

Automated Systems at BL44B2: “To achieve high-throughput protein crystallography, we have developed two special components: an automated sample changer robot, SPACE (SPring-8 precise auto-matic cryo-sample exchanger) (Ueno, Hirose et al., 2004), which can change up to 100 crystals in a diffractometer, and the beamline control software BSS (beamline scheduling software) (Ueno et al., 2005), which can perform successive data collection by controlling beamline devices, including SPACE, and managing the data collection schedule. The combination of SPACE and BSS enables unmanned overnight data collection and allows the beamline to operate with high efficiency.”2
