Zusammenfassung:The design and commissioning of an inelastic X‐ray scattering instrument at CMC‐XOR at the Advanced Photon Source is reported. The instrument features a 2 m vertical‐scattering arm with a novel counterweight design to reduce the twisting moment as the arm is moved in the scattering plane. A Ge(733) spherical analyzer was fabricated and an overall resolution of 118 meV (FWHM) was obtained with a Si(444) monochromator and a Si(111) pre‐monochromator. Early results from a representative cuprate, La2CuO4, are reported.
