Control of ion drag in a dusty plasma

The influence of a mixture of light and heavy gases, i.e., helium and argon, on plasma-dust structures in the radiofrequency discharge has been studied. The dust chains in the sheath of the radiofrequency discharge, the average distance between the dust particles and their chains, have been analyzed. A significant effect of small amounts of argon on the correlation characteristics of dust particles has been observed. The results of numerical simulation of ion and electron drift in the mixture of helium and argon are presented. It is shown that even 1% of argon admixture to helium produces such an effect that argon ions become the main components of the discharge, as they drift with lightweight helium forming a strongly anisotropic velocity distribution function.

“…Conditions of phase transitions at additive of krypton in helium were investigated in [16]. A possibility of controlling of dynamics of dust structures in the mixture of xenon and helium was studied in [17]. In a number of works a wake-effect was found [18,19]; an area of ion focusing was formed behind a single granule downstream of ions flux.…”

The research of dust structures dynamics in striations of the glow discharge in the magnetic field in the mixture of gases is presented. A variation of an ion flux velocity at an additive in light plasma forming gas of a small changeable portion of heavy and easily ionized components makes the control of ion drag force. It is shown that the small part of xenon (up to 5 percent) changes the static and dynamic properties of dust structure essentially. The increase of angular velocity of dust structure is revealed upon transition from pure helium to the mixture with small impurity of xenon. A reduction of vertical interpartical distance in dust structure in the mixture with xenon is detected. Results are agreed with data of calculation of characteristics of drift of ions in mixtures of gases.

“…These are the ion drag force and the dragging by the rotating gas owing to the Ampère force associated with the component of eddy current directed radially from the discharge axis. The experiment [20] in which the ion drag force was varied allows us making the choice between the models in this area of the discharge.…”
