One is the SIOM National Laboratory on High Power Laser Physics, and the other is the SIOM Key Laboratory for High Intensity Optics. In the afternoon, he gave a research lecture titled "Synchrotron X-ray diffraction with resonant scattering in crystal and its topography study". Prof.Riichrou Negishi reported his latest research on Synchrotron X-ray diffraction with resonant scattering in crystal. After the lecture, Prof.Riichrou Negishi had a hot discussion with 35 researchers from SIOM.
