在磁约束环形等离子体中，局部发射强度，温度和流速的原子在内侧和外侧的刮削层可以分别测量被动发射光谱辅助观察塞曼分裂在其谱线形状。为了利用这一技术，我们研制了一台用于观测氦2（3）S-2（3）P跃迁谱线（波长1083 nm）的近红外干涉光谱仪。该技术的实际环面设备的适用性阐明通过计算预期将在LHD和QUEST（Q-shu大学实验与稳态球形托卡马克）观察到的谱线形状。此外，塞曼效应对谱线形状的测量使用辉光放电管安装在超导磁体。
In magnetically confined torus plasmas, the local emission intensity, temperature, and flow velocity of atoms in the inboard and outboard scrape-off layers can be separately measured by a passive emission spectroscopy assisted by observation of the Zeeman splitting in their spectral line shape. To utilize this technique, a near-infrared interference spectrometer optimized for the observation of the helium 2(3)S-2(3)P transition spectral line (wavelength 1083 nm) has been developed. The applicability of the technique to actual torus devices is elucidated by calculating the spectral line shapes expected to be observed in LHD and QUEST (Q-shu University Experiment with Steady State Spherical Tokamak). In addition, the Zeeman effect on the spectral line shape is measured using a glow-discharge tube installed in a superconducting magnet.
