Inelastic X‐ray scattering is a powerful and versatile technique for studying lattice dynamics in materials of scientific and technological importance. In this article, the design and capabilities of the momentum‐resolved high‐energy‐resolution inelastic X‐ray spectrometer (HERIX) at beamline 30‐ID of the Advanced Photon Source are reported. The instrument operates at 23.724 keV and has an energy resolution of 1.3–1.7 meV. It can accommodate momentum transfers of up to 72 nm −1 , at a typical X‐ray flux of 4.5 × 10 9 photons s −1 meV −1 at the sample. A suite of in situ sample environments are provided, including high pressure, static magnetic fields and uniaxial strains, all at high or cryogenic temperatures.
