| 内容記述 | 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 scattering signals. After applying this method to a relatively low density LHD plasma, the scattering of electron temperature profiles becomes small. The magnitude of error is also reduced by 1/2 at some positions. Simulations of signals with some noises based on the JT-60SA Thomson scattering system enables showing expected error in electron temperature. The error can be suppressed by the ”model fitting” method. | |||||
