Influence of gas mixtures on complex plasmas parameters in rf and dc discharges
Keywords:
radio-frequency capacitive discharge, mixture of gases, combined RF DC dischargeAbstract
In this paper the influence of the gas mixture on plasma parameters in DC and combined RF+DC discharge is studied. Тhe properties of complex plasma in the radio-frequency discharge of the gas mixture, with additional constant electrostatic field were experimentally studied. It is shown that the addition of a heavy gas to a light one, and the additional impact of a constant field on the RF discharge leads to changes in the spatial characteristics of the buffer plasma and, hence, the location of the dust structure.
