Instrumental upgrades of the RIXS spectrometer at BL11XU at SPring-8

Two recent instrumental upgrades of the inelastic X-ray scattering spectrometer installed at BL11XU at SPring-8 are reported. The first one is a multianalyzer system, where we can simultaneously use three crystal analyzers aligned perpendicularly to the scattering plane. In a test measurement of polycrystalline $$alpha$$-PtO$$_2$$, the inelastic spectra obtained with each respective analyzer showed a completely identical lineshape, and a slight difference ($$le$$ 10%) in intensity. The system enhances the experimental efficiency, and allows for simultaneous scan at three momenta for a single-crystal sample. The second development is a polarization analyzer for the scattered photons. A pyrolytic graphite (PG) crystal is placed in front of the detector and serves as a polarization-analyzer crystal, using the (006) reflection for the Cu $$K$$-edge. We succeeded to observe clear polarization dependence in the $$d$$-$$d$$ excitations of KCuF$$_3$$.
