Specific Synchrotron Radiation Facilities Users Community (SpRUC)

The X-ray Topography Research Group aims to advance the science and related engineering of techniques that visualize the real-space distribution of higher-order structures in crystalline materials by exploiting X-ray diffraction and scattering phenomena, as well as to promote the effective use of such techniques.

In developing advanced X-ray topography methods, we fully leverage the key characteristics of SPring-8 synchrotron radiation?high intensity, high brightness, high energy, and high coherence?to achieve substantial improvements in spatial resolution, temporal resolution for real-time observations, and contrast. We also seek to greatly expand the applicability of the developed techniques and methodologies to targets that have been difficult to observe and evaluate by conventional approaches.

Furthermore, we will collaborate not only as a user group of SPring-8 but also with users of other synchrotron radiation facilities such as the Photon Factory. Through these activities, we will provide recommendations to synchrotron facilities and promote further development of X-ray topography technologies.

During the 7th term, we proceeded with the installation of a high-throughput X-ray topography measurement system at BL16B2, and the system became available for general user operation starting in autumn 2025. In the 8th term, taking into account the transition to SPring-8-II, we will gather user requests and further upgrade and enhance the instrumentation.
