Development of a neural network-based model for electron temperature inference via modelled and experimental argon spectra measured by x-ray crystal spectrometer with an extension to tungsten spectra on EAST

Accurate inference of electron temperature ( T _e ) profiles is essential for understanding energy transport and impurity dynamics in magnetic confinement fusion plasmas. Traditional spectral diagnostics based on satellite line ratios become unreliable in high- T _e regimes due to reduced line inten...
