RIKEN SPring-8 Center SR Life Science Instrumentation Team

Team Leader: Masaki Yamamoto (Ph.D.)

Research Summary

Masaki  Yamamoto(Ph.D.)

SR Life Science Instrumentation Team has mission of research and development of new technologies for structural biology and beamlines at SPring-8 site. Our mission includes technologies on instrumentation of beamline optics, experimental station, sample handling and X-ray detectors, and methodologies on data collection and structure determination by using SPring-8 or SACLA. Moreover, our team is responsible for the operation of four RIKEN structural biology beamlines (BL32XU, BL26B1&B2, and BL38B1). The methodology development on damage-free crystallography and X-ray coherent diffraction cryo-imaging based on ultra-bright and short pulse beam of SACLA for life science research is going on.
