چکیده
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 dust particle surface and discharge tube wall are taken into account. The results show that the densities of metastable argon atoms and dust particles are in strong correlation, and both sufficiently influence gas discharge parameters.

Influence of dust particles on ionization and excitation in neon dc discharge
The influence of dust particles on the concentration of metastable neon atoms and ionization was investigated using the developed drift/diffusion model for plasma of positive column of glow discharge. The detailed de-excitation in neon was considered. In addition to usual plasma losses in dusty plasmas, the quenching of metastable atoms on dust particle surface was considered. The strong influe...
متن کاملMeasured density of copper atoms in the ground and metastable states in argon magnetron discharge correlated with the deposition rate
In a dc-magnetron discharge with argon feed gas, densities of copper atoms in the ground state Cu(S1/2) and metastable state Cu*(D5/2) were measured by resonance absorption technique, using a commercial hollow cathode lamp as light source. The operating conditions were 0.3 14 μbar argon pressure and 10 200 W magnetron discharge power. The deposition rate of copper in a substrate positioned at 1...
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 ...

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...
