Abstract
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.
Highlights
The plasma can be described by the corona model if the distribution of the excited states populations can be fitted with the following expression with x ≤ 322: Ni(pi ) α gi(pi )
A visible spectro-tomographic diagnostic installed on the Mistral experiment is presented
It is an update of a previous tomographic setup[14,17]
