英文摘要Based on the passive spectroscopy, the D a 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 a spectral lines has been observed. A fitting procedure by using a nonlinear least squares method was applied to fit and analyze all polarization pi and +/-sigma components of the D a atomic spectra to acquire the information of the local plasma. The spectral line shape was investigated according to emission spectra from different regions (e.g., low-field side and high-field side) along the viewing chords. Each polarization component was fitted and classified into three energy categories (the cold, warm, and hot components) based on different atomic production processes, in consistent with the transition energy distribution by calculating the gradient of the D a spectral profile. The emission position, magnetic field intensity, and flow velocity of a deuterium atom were also discussed in the context.
