The Au-coated toroidal mirror used in the present work (340 × 60 × 40 mm). (a) The mirror before cleaning, contaminated by synchrotron-radiation-induced carbon contamination. (b) The mirror after cleaning using an RF plasma at 10 W for 1 h. The symbols R1 to R12 indicate the points along the mirror length where the Raman spectra were measured.
