The influence of the cross section of the electron-copper atom collision on the electrical conductivity of Ar-Cu and SF₆-Cu plasmas

Abstract

The electrical conductivity of SF6-Cu and Ar-Cu plasmas has been calculated by using new values of the cross section of the electron-copper momentum transfer. The comparison between the new values of the electrical conductivity and the previous ones, in the temperature range 2500-15000 K, shows the actual influence of copper vapour on this transport coefficient and allows quantification of the errors made with the various approximations.

Application of Microwave Beam Refraction in Inhomogeneous Plasma Interferometry

“…2 to 9. One can see that the properties of the water-vapor discharge plasma with metal impurities substantially [16] (2 ), alternative model [18] (3 ), and non-resonance model [17] (4 ) depend on the plasma composition. As a rule, the appearance of metal impurities gives rise to the growth of conductivity and energy density in plasma.…”

“…In work [15], various models for the cross-section of electron-copper atom collisions and the results of their application to simulate a low-temperature plasma were discussed in detail. The most widespread models for the crosssection of low-energy electron scattering by a copper atom are the following ones: the resonance model [16], which is characterized by the presence of a resonance near 0.1 eV, and the non-resonance one [17]. However, the results of calculations in the framework of a new alternative model were reported recently [18].…”

A multiphase model for pulsed ns-laser ablation of copper in an ambient gas

“…Here n K and σ K are the number density of the vapor species and the momentum transfer cross section, respectively. The momentum cross section is in the order of 10 −18 m 2 [59].…”
