(a) Schematic of a conventional energy-dispersive RIXS setup with a diced spherical analyzer A, a strip detector D, and sample S in a Rowland circle geometry (dashed). Extrinsic elastic scattering from point S′ ≠ S arrives at the detector at F′ ≠ F and is therefore counted at a different energy. (b) Schematic of a conventional RIXS setup with a bent spherical analyzer A. Scattered X-rays from S and S′ will be focused on different single points at F and F′ and therefore do not interfere with each other. |
