(a) SXC-RIXS spectrometer in the `MCA' configuration, consisting of a collimating mirror M (laterally graded Ru/C multilayer Montel mirror), a collimating crystal C [asymmetrically cut Si (111)], and the analyzer A [symmetrically cut Si (844) or sapphire (078) crystal]. The 1D strip detector (MYTHEN) collects photons reflected by the analyzer A. (b) One-step collimating configuration `MA' that does not include a C-crystal. (c) The diamond anvil cell high-pressure sample environment. A sample is contained in a space surrounded by diamond anvils and a Be gasket with Ne gas as a pressure medium and ruby chips for pressure monitoring. The X-rays pass through the Be gasket, which is relatively transparent to X-rays. |
