Experimental check of the high-frequency behavior of the electrons in molecular and atomic gas plasmas

Microwave Diagnostics of the Electron Density in Molecular Mixture Plasmas

“…Further aspects with regard to the suitable manner for performing the microwave measurements are detailed in Refs. [6,7].…”

“…In general, the phase delay has been obtained according to Eq. (4) and the relation σ In this approach the time-independent distribution F 0 (U) is determined by solving an appropriate steady-state kinetic equation for F 0 (U) [6,7] for selected field parameters (ω/p 0 , E/p 0 and E 2 hf 6, where the measured admixture ratios and reduced electric field strengths given in Figs. 2 and 3, respectively, have been used.…”

“…For the field frequency region considered in this paper the angular frequency ω of the electric field becomes larger than the lumped frequency ν e (U) for energy dissipation by collisions of electrons with the neutral gas particles. As detailed in former papers [6,7], then the periodic current density of the electrons can be expressed by…”
