Kinetics of N2(B3Πg) and N2(C3Πu) states in N2-Ar discharges sustained by a RF helical coupling device
Résumé
A kinetic model is discussed for the two main emitting species (N2(B), N2(C)) of a N2-Ar plasma excited at 27 MHz by a helical cavity with operating pressure of 200 Pa. The present paper consistently illustrates, for miscellaneous Ar fractions and different positions, the great influence of the processes involving the metastable species (N2(A), Arm) and the electrons on the kinetics
