Space and time resolved spectroscopic characterization of Pulsed Atmospheric Plasma Streams for biomedical applications
Résumé
In the framework of the optimization of Plasma Gun [1] biomedical potentialities, parametric study showing dependency of reactive species production to gas flow and repetition rates had been achieved by means of Optical Emission Spectroscopy (OES) and fast imaging. To complete characterization, gas temperature estimation, using rotational structures of N2* (C3Πu-B3Πg) 2nd+ system as well as determination of the electron density by the Stark broadening of Hβ line have been performed. Due to the limit of procedure at atmospheric pressure, electron density had been also evaluated thanks to current measurements and had been compared to Hem (23S) metastable state density measured by tunable diode laser absorption spectroscopy (TDLAS).
