Development of signal analysis method for the motional Stark effect diagnostic on EAST

A pilot single-channel Motional Stark Effect(MSE) diagnostic has been developed on EAST since 2015. The dual photo-elastic modulators(PEM) were employed to encode the polarization angle into a time-varying signal. The pit  (本文共4页) 阅读全文>>

Development of the simulation platform between EAST plasma control system and the tokamak simulation code based on Simulink

Plasma control system(PCS),mainly developed for real-time feedback control calculation,plays a significant part during normal discharges in a magnetic fusion device,while the tokamak simulation code(TSC) is a nonlinear numerical model that studies the time evolution of an axisymmetric magnetized tokamak plasma.The motivation to combine these two codes for an integrated simulation is specified by the facts that the co...  (本文共10页) 阅读全文>>

Analysis of the Zeeman effect on D_α spectra on the EAST tokamak

Based on the passive spectroscopy,the D_α atomic emission spectra in the boundary region of the plasma have been measured by a high resolution optical spectroscopic multichannel analysis(OSMA) system in EAST tokamak.The Zeeman splitting of the D_α spectral lines has been observed.A fitting procedure by using a nonlinear least squares method was applied to fit and analyze all polarization π and ±σ components of t...  (本文共7页) 阅读全文>>
