X-rays have played a vital role in a number of breakthrough scientific discoveries in recent years. Continuous innovations in X-ray optics, methodologies, and beamline instruments have laid the foundation for these achievements. For this conference, we are inviting leading experts in these fields from around the world to share the latest status of X-ray technology and developments and to discuss their plans for the future. One important topic we would like to discuss is how state-of-the-art X-ray optics can contribute to exploring the potential of the DLSR (Diffraction-Limited Synchrotron Radiation) sources that are currently emerging.
