Characterization of a DC glow discharge in with electrical measurements and neutral and ion mass spectrometry
Audrey Chatain, Ana Sofia Morillo-Candas, Ludovic Vettier +3
The addition of small amounts of were investigated in a DC glow discharge in , at low pressure (~1 mbar) and low power (0.05 to 0.2 ). We quantified the elect…
Interaction dust-plasma in Titan's ionosphere: feedbacks on the gas phase composition
Audrey Chatain, Nathalie Carrasco, Ludovic Vettier +1
Titan's organic aerosols are formed in the ionosphere, a layer ionized by solar VUV photons and energetic particles from the magnetosphere of Saturn, forming a natural N2-CH4-H2 pl…
Validation of non-equilibrium kinetics in CO2-N2 plasmas
C. Fromentin, T. Silva, T. C. Dias +3
This work explores the effect of N2 addition on CO2 dissociation and on the vibrational kinetics of CO2 and CO under various non-equilibrium plasma conditions. A self-consistent ki…
Study of vibrational kinetics of CO2 and CO in CO2-O2 plasmas under non-equilibrium conditions
C. Fromentin, T. Silva, T. C. Dias +4
This work explores the effect of O2 addition on CO2 dissociation and on the vibrational kinetics of CO2 and CO under various non-equilibrium plasma conditions. A self-consistent mo…
Re-Analysis of the Cassini RPWS/LP Data in Titan's Ionosphere: 2. Statistics on 57 Flybys
A. Chatain, J. -E. Wahlund, O. Shebanits +5
The ionosphere of Titan hosts a complex ion chemistry leading to the formation of organic dust below 1200 km. Current models cannot fully explain the observed electron temperature…
Re-Analysis of the Cassini RPWS/LP Data in Titan's Ionosphere: 1. Detection of Several Electron Populations
A. Chatain, J. -E. Wahlund, O. Shebanits +5
Current models of Titan ionosphere have difficulties in explaining the observed electron density and/or temperature. In order to get new insights, we re-analyzed the data taken in…
N2-H2 capacitively coupled radio-frequency discharges at low pressure. Part II. Modelling results: the relevance of plasma-surface interaction
Miguel Jiménez-Redondo, Audrey Chatain, Olivier Guaitella +4
In this work, we present the results of simulations carried out for N2-H2 capacitively coupled radio-frequency discharges, running at low pressure (0.3-0.9 mbar), low power (5-20 W…
N2-H2 capacitively coupled radio-frequency discharges at low pressure. Part I. Experimental results: effect of the H2 amount on electrons, positive ions and ammonia formation
Audrey Chatain, Miguel Jiménez-Redondo, Ludovic Vettier +5
The mixing of N2 with H2 leads to very different plasmas from pure N2 and H2 plasma discharges. Numerous issues are therefore raised involving the processes leading to ammonia (NH3…
Interaction dust-plasma in Titan's ionosphere: an experimental simulation of aerosols erosion
Audrey Chatain, Nathalie Carrasco, Nathalie Ruscassier +3
Organic aerosols accumulated in Titan's orange haze start forming in its ionosphere. This upper part of the atmosphere is highly reactive and complex ion chemistry takes place at a…
