| 内容記述 | Thomson scattering diagnostics provide electron temperature (Te) and density profiles in plasmas. They require measurements the scattered light, which are pulses with 10-100ns short, using fast digitizers. As a signal processing method for the fast digitizers, ”mode fitting” method is proposed for the switched-capacitor-type digitizers, such as CAEN V1742 and TechnoAP boards. ”Model fitting” is applied for a relatively low density LHD plasma. Te values and the magnitude of errors become small by this method. Simulating of signals with some noises based on the JT-60SA Thomson scattering system enables showing expected error in Te. The error can be suppressed by a model fitting method. | |||||
