Abstract: A two‐dimensional resonant inelastic X‐ray scattering (2D‐RIXS) microscopy system has been developed at beamline BL02U of NanoTerasu. The instrument combines a Wolter type‐I mirror for spatial imaging with a varied‐line‐spacing grating spectrometer, simultaneously achieving micrometre‐scale spatial resolution and ultrahigh energy resolution in the soft X‐ray regime. Test chart measurements confirm a vertical spatial resolution of 1.0 µm near the field‐of‐view center, and the horizontal resolution determined by the incident beam footprint is 0.8 µm. RIXS imaging capabilities have been demonstrated by the measurements of a patterned NanoTerasu logo and exfoliated NiPS3 nanoflakes, highlighting its efficiency in locating specific microscale regions within inhomogeneous samples. These results establish 2D‐RIXS microscopy as a position‐sensitive probe of elementary excitations in quantum materials and functional devices. [ABSTRACT FROM AUTHOR]
