Definition of a new level-one test case - measurements of equilibrium radiation from an inductively coupled plasma in the near-UV to near-IR spectral region for a martian-type CO2-N2 mixture

Résumé

A new test case, using a quasi-similar methodology and experimental set-up than previous test case 1, is presented in this paper. An inductively coupled plasma torch, working at atmospheric pressure, is used to create CO2-N2 Martian-like plasma (97% CO2, 3% N2). The operating frequency and power are 64 MHz and 3 kW respectively. This kind of apparatus allows obtaining plasma in chemical and quasi-thermal equilibrium. The plasma characterization will consist firstly to determining the chemical composition; a calculation code based on the Gibbs free energy minimization is used. Secondly, the radial temperature profiles will be given through Abel inversion of atomic and molecular systems. The spectral measurements cover the [250-800] nm range and are performed inside the induction coil. Each interesting spectrum is Abel-inverted and calibrated in order to determine the volumetric emission coefficient. These spectra are then compared to the line-by-line spectral code SESAM used for the simulation of the radiative emission of entry-type plasma.
