Degradation of CO2,N2and He mixtures at low pressure monitored via wave instabilities

摘要: Glow discharge plasma in atomic and molecular gases their mixtures at low pressure is prone to spontaneous inception of wave instabilities (moving striations). They result from different transport processes between electrons neutral gases. The predominance some process reflected phase group velocities a particular instability which, turn, can be used for detecting the internal kinetics. In our case ionization-thermal diffusion waves have been monitor final temporal degradation CO2, N2 He mixture direct current glow discharge.
