Abstract
For measuring the plasma ion temperature profile in the L-2M stellarator, passive spectroscopic diagnostic system in the visible spectral range was developed. The ion temperature profile in the ohmic heating regime was reconstructed using data on the Doppler broadening of the impurity ion lines: C III (464.7 nm), O II (441.5 nm), and O II (441.7 nm). Original computational code was developed for reconstructing the ion temperature profile. The radial intervals of correct reconstruction of the ion temperature profiles extend from the maximum of the radial intensity distribution of the corresponding lines to the plasma boundary. The ion temperature profiles reconstructed from the spectra of the C III (464.7 nm) and O II (441.5 nm) lines are in good agreement with each other.
为了测量L-2M仿星器内等离子体离子温度分布，研制了可见光谱范围的无源光谱诊断系统。利用杂质离子线的多普勒展宽数据重建了欧姆加热区离子温度分布：C III （464.7 nm）、O II （441.5 nm）和O II （441.7 nm）。为重建离子温度分布，开发了原始的计算程序。正确重建离子温度分布的径向间隔从对应谱线的径向强度分布的最大值延伸到等离子体边界。由Cⅲ（464.7 nm）和Oⅲ（441.5 nm）谱线重建的离子温度分布具有较好的一致性。
