Spatially resolved determination of the electronic density and temperature by a visible spectrotomography diagnostic in a linear magnetized plasma
摘要：
在这项工作中，一个非侵入性的，空间分辨，光谱层析光学诊断的电子密度和温度的线性等离子体柱西北风。光谱学和层析成像技术的耦合提供了在不同波长（可见光和近红外）的氩等离子体中的局部等离子体光发射的访问。利用Mistral实验的对称性，验证了诊断结果，发现等离子体对应于日冕平衡态。与使用另一个光谱仪和朗缪尔探针，我们提出了一种非侵入性的方法来确定电子密度和温度的等离子体的断层图像的每个像素。所得结果与朗缪尔探针的结果符合得很好。
英文摘要：
In this work, a non-intrusive, spatially resolved, spectro-tomographic optical diagnostic of the electronic density and temperature on the linear plasma column Mistral is presented. Coupling of spectroscopy and tomography technique gives access to the local plasma light emission at different wavelengths (visible and near IR) in an argon plasma. Taking advantage of the symmetry of the Mistral experiment, the diagnostic results are validated and the plasma is found to correspond to a corona equilibrium state. With the use of another spectrometer and a Langmuir probe, we propose a non-intrusive method to determine the electronic density and temperature of each pixel of the tomographic images of the plasma. The obtained results are in good agreement with the Langmuir probe ones.
