As a signal processing method for fast digitizers of the switched-capacitor-type in the Thomson scattering diagnostics, the ”mode fitting” method is proposed. An ideal shape of the signal is estimated in this method by averaging many Thomson scat

This paper reports the gamma-ray irradiation effects on optical coatings and polarizers to be used in the ITERedge Thomson scattering system (ETS). Outside a diagnostic port-plug, in the Interspace, a total dose of the orderof 1 MGy is expected throu
