Resonant inelastic X‐ray scattering in the XUV‐regime has been implemented at BESSY II, pushing for a few‐meV bandwidth in inelastic X‐ray scattering at transition metal M ‐edges, rare earth N ‐edges and the K ‐edges of light elements up to carbon with full polarization control. The new dedicated low‐energy beamline UE112‐PGM1 has been designed to provide 1 µm vertical and 20 µm horizontal beam dimensions that serve together with sub‐micrometre solid‐state sample positioning as the source point for a high‐resolution plane grating spectrometer and a high‐transmission Rowland spectrometer for rapid overview spectra. The design and commissioning results of the beamline and high‐resolution spectrometer are presented. Helium autoionization spectra demonstrate a resolving power of the beamline better than 10 000 at 64 eV with a 300 lines mm −1 grating while the measured resolving power of the spectrometer in the relevant energy range is 3000 to 6000.
