论文摘要
在这项工作中,提出了线性等离子体柱上的电子密度和温度的非侵入性,空间分辨,光谱光学诊断。光谱和断层扫描技术的耦合可在氩等离子体中访问不同波长(可见的IR)局部等离子体光发射。利用Mistral实验的对称性,诊断结果得到了验证,并且血浆被发现与电晕平衡状态相对应。通过使用另一个光谱仪和langmuir探针,我们提出了一种非侵入性方法来确定等离子体层析图像的每个像素的电子密度和温度。获得的结果与Langmuir探测器非常吻合。
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.
