abstract = {{The integration of an X-ray Raman spectroscopy (XRS) spectrometer and a Resonant Inelastic X-ray scattering (RIXS) spectrometer at HEPS is described. The XRS has 6 regular modular groups and 1 high resolution modular group. In total 90 pieces of spherically bent analyzer crystals are mounted in low vacuum chambers with pressure lower than 100Pa. On the other hand, the RIXS spectrometer possesses one spherically bent analyzer crystal configured in Rowland geometry whose diameter is changeable from 1m to 2m. The scattering X-ray photons transport mostly in helium chamber to reduce absorption by air. The RIXS and the high resolution module can be exchanged when needed. Six air feet are set under the granite plate to unload the weight when the heavy spectrometer is aligned. The natural frequency and statics of the main granite rack were analyzed and optimized to maintain high stability for the HEPS-ID33 beamline at the 4th generation source. A type of compact and cost-effective adjustment gadget for the crystals was designed and fabricated. Economic solutions in selection of motors and sensors and other aspects were adopted for building the large spectrometer like this.}},
