SACLA produces X-ray pulses billion times brighter than synchrotron radiation sources. SACLA has a potential to change life-science, particular structural biology, revolutionary. The user operation of SACLA has started and now it's critical to develop data collection systems focusing on specific scientific areas. Recently, we are developing a data collection system focusing on dynamic crystallography putting a particular effort on membrane proteins. An experimental system for pump-probe experiments based on serial femtosecond crystallography using a viscous material injector has been developed to visualize conformational changes in bacteriorhodopsin (bR) from nanoseconds to milliseconds following photoactivation.
