BEAMLINE GUIDE
SPring–8 BL41XU

Super Photon ring-8 GeV
Japan
SPACE Automounter

A macromolecular crystallography beamline BL41XU allows for diffraction experiment by using the photon flux of the 2.2 × 1012 〜 1.1 × 1013 (photons/s@1 Å) which is the highest level in the world. The beamline is mainly used for the structural determination of challenging targets such as membrane proteins and macromolecular complexes which are usually difficult to make well diffracting crystals. Since the beam size can be changed from 4 × 5 to 22(H) × 45(V) µm2, it can cope with various samples whose size is from a few micrometer to several hundreds micrometer. Another characteristic feature of BL41XU is that it allows for data collection using high energy X-ray from 19 keV to 35 keV. 1

Automated Systems at BL41XU:

“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
