Corentin Bajon studies reaction mechanisms of dielectric barrier discharges

French Ph.D. student Corentin Bajon has arrived at the Department of Physical Electronics and CEPLANT for the second time within the MOBILITY project. His research focuses on dielectric barrier discharges in carbon dioxide atmosphere and understanding various reaction mechanisms of said discharge.

Corentin Bajon, a Ph.D. student from Université Toulouse III - Paul Sabatier in French Toulouse, is on his second stay at the Department of Physical Electronics and CEPLANT. His exchange stay is through the Czech MEYS Mobility program called Study of the dielectric barrier discharge in CO2. Corentin studies Physique des Plasmas and cooperates with Le Laboratoire Plasma et Conversion d’Energie (LAPLACE). At the DPE, Corentin will stay for five weeks at the research group Plasma Diagnostics and Modeling of Assoc. Prof. Tomáš Hoder. He will continue his research of the dielectric barrier discharge in the CO2 atmosphere here in Brno. His results will be a part of his dissertation thesis and joint scientific publications.

In the scope of the Mobility project, the scientists will, for the first time, characterize the homogeneous discharge at atmospheric pressure in the atmosphere of carbon dioxide and make a systematic comparison with discharges working in filamentary modes. This research enables the study of reaction mechanisms in these discharges (excitation and dissociation from direct electron impact, subsequent excitation mechanisms, and others). Corentin also deals with the precision quantification of CO2 dissociation rate in various modes of discharge operation using infrared absorption. He will identify the dominant mechanism in these discharges using chemical kinetic models.

Why does Corentin do his research at the Department of Physical Electronics here with us in Brno? His Ph.D. thesis is under dual supervision. He works with the guidance of Nicolas Naudé from Toulouse and Tomáš Hoder from MUNI. His university does not have the necessary equipment to study nanosecond dielectric barrier discharges in the CO2 atmosphere. We have asked Corentin few questions about his research and stay.
