A new resonant inelastic X‐ray scattering (RIXS) instrument has been constructed at beamline P01 of the PETRA III synchrotron. This instrument has been named IRIXS (intermediate X‐ray energy RIXS) and is dedicated to X‐rays in the tender‐energy regime (2.5–3.5 keV). The range covers the L 2,3 absorption edges of many of the 4 d elements (Mo, Tc, Ru, Rh, Pd and Ag), offering a unique opportunity to study their low‐energy magnetic and charge excitations. The IRIXS instrument is currently operating at the Ru L 3 ‐edge (2840 eV) but can be extended to the other 4 d elements using the existing concept. The incoming photons are monochromated with a four‐bounce Si(111) monochromator, while the energy analysis of the outgoing photons is performed by a diced spherical crystal analyzer featuring (10 2 ) lattice planes of quartz (SiO 2 ). A total resolution of 100 meV (full width at half‐maximum) has been achieved at the Ru L 3 ‐edge, a number that is in excellent agreement with ray‐tracing simulations.
