Abstract/Summary This paper presents the characterization of an inductively coupled CO2 plasma relevant for Mars entry. Key plasma parameters are measured using Two Photon Absorption LaserInduced Fluorescence (TALIF), Optical Emission Spectroscopy (OES) and a High-Speed Camera (HSC) as non-intrusive diagnostic methods. In addition heat flux, enthalpy and total pressure are intrusively probed to supplement the characterization. TALIF provides data about translational temperature, velocity and the density of ground state atomic oxygen. From OES rotational and vibrational temperatures for identified molecular species and excitation temperatures for atomic species are derived. Preliminary HSC results show the pulsing behaviour of the generator and, in combination with bandwidth filters, atomic emission distributions. The diversity of the applied measurement techniques offers an extensive characterization of the flow, hence enabling the identification of suitable test conditions for the early stages of Martian entries.
