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.}, pages = {2402032-1--2402032-4}, title = {Fast signal modeling for Thomson scattering diagnostics and effects on electron temperature evaluation}, volume = {17}, year = {2022} }
