Influence of Xenon–Fluorine–Sulfur Hexafluoride (<i>Xe</i>⁺–<i>F</i>⁻–<i>SF</i>6⁻) and Argon-Fluorine-Sulfur Hexafluoride (<i>Ar</i>⁺–<i>F</i>⁻–<i>SF</i>6⁻) Streaming on Dust Surface Potential (DSP) That Has Cairn–Tsallis Distributed Plasmas

Abstract

The dust grain surface potential is examined analytically and numerically in dusty plasmas containing negative/positive ion species by using the Cairn Tsallis (non-Maxwellian) dusty plasma. The equations for the dust-charging process are derived to solve the current balance equation for the xenon–fluorine–sulfur hexafluoride and argon–fluorine–sulfur hexafluoride plasmas. The charging process affected by plasma properties such as spectral indices α and q, in addition to positive ion streaming (UAr+ and UXe+) and negative ion streaming (UF− and USF6−) of both types of plasmas, is examined. Our findings suggest that considering a wide range of Xe+−F−−SF6− and Ar+−F−−SF6− masses is critical for understanding plasma physics, specifically multi-component plasmas.
