Influence of Metastable Argon Atoms and Dust Particles on Gas Discharge Plasma
The model of a DC glow discharge with metastable argon atoms and dust particles based on the Boltzmann equation for the electron energy distribution function (EEDF), dust particle charging, and balance equation for metastable argon atoms is presented. The processes of direct and stepwise electron impact ionization, metastable-metastable collisions, and recombination of electrons and ions on the...
متن کاملThe role of carrier gases in the production of metastable argon atoms in a rf discharge.
We investigate the role of carrier gases in the production of metastable argon atoms in a rf-driven discharge. The effects of different carrier gases (krypton, xenon, neon, and helium), carrier gas pressures, and rf discharge powers are examined. A xenon carrier gas provides the greatest metastable population of argon, yielding an optimal fractional metastable population of argon (Ar(*)/Ar) of ...
متن کاملProduction of argon metastable atoms in high pressure (20-300 Torr) microwave discharges
2014 The production of Ar(3P2) metastable atoms has been determined in high pressure (20-300 Torr) and low power (5-30 W) argon 2.45 GHz microwave discharges. The following plasma parameters have been measured : the gas temperature, deduced from the rotational spectra of CN radical in impurity in argon, was found between 380 K (20 Torr, 5 W) and 840 K (300 Torr, 30 W) ; the Ar (3P2) concentrati...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
