Resonant Inelastic X-ray Scattering (RIXS) in the soft x-ray range is an element-specific energy-loss spectroscopy used to probe electronic and magnetic excitations strongly correlated solids. In recent years, RIXS has been progressing very quickly terms of energy resolution understanding experimental results, but interpretation spectra could further improve, sometimes decisively, from a full knowledge polarization incident scattered photons. Here we present first implementation, high soft-RIXS spectrometer analyze radiation, device allowing measurement degree linear polarization. The system, based on graded W/B4C multilayer mirror installed proximity CCD detector, AXES at ESRF (European Synchrotron Radiation Facility); it fully characterized for demonstration experiment Cu L3 edge high-Tc superconducting cuprate. loss efficiency suffered by equipped with this test facility was factor 17.5. We propose also more advanced version, suitable routine use next generation spectrometers overall up 10%.
