The NanoTerasu public beamline achieves the world’s highest energy resolution

Principal researcher Jun Miyawaki and his colleague at the NanoTerasu Center have developed equipment for resonant inelastic X-ray scattering (RIXS) experiments at the public beamline BL02U of the NanoTerasu. They achieved a world-leading performance with an energy resolution of 16.1 meV, significantly surpassing the previous record of 22 meV. This breakthrough also improved the efficiency of the measurements.
