Experimental Investigations of Dusty Plasmas
This paper highlights some of the history of laboratory experiments in dusty plasmas, beginning with an early unexpected discovery of Langmuir. Although there was a great deal of theoretical work on dusty plasmas long before dedicated laboratory experiments were initiated, the experimental work is catching−up and new discoveries in the laboratory are motivating further theoretical work.
متن کاملMagnetoplasmons in rotating dusty plasmas.
A rotating dusty plasma apparatus was constructed to provide the possibility of experimental emulation of extremely high magnetic fields by means of the Coriolis force, observable in a corotating measurement frame. We present collective excitation spectra for different rotation rates with a magnetic induction equivalent of up to 3200 T. We identify the onset of magnetoplasmon-equivalent mode di...
متن کاملPhase Transition in Dusty Plasmas:
We report on analytical and simulat n studies of mi ophy processes that trigger phase transitions in a dusty plasma subject to ion streaming. For res below the critica ure Pc for condensation, the grains acquire a large random kinetic energy and form a we upled fluid. P is increased to greater than Pc, the grains lose their kinetic energy and reach a strongly coupled crystal e state. The ust he...
متن کاملRadiometric force in dusty plasmas.
It is shown that inhomogeneous heating of the dust grain by ion flow in a glow discharge results in a photophoresislike force. According to our estimations, this radiometric force can be comparably-valued with the ion-drag force under the conditions of microgravity dusty plasma experiments.
متن کاملStatistical Properties of Relaxing Dusty Plasmas
The Liouville equation is considered for relaxing dusty plasmas consisting initially of equilibrium electrons and ions as well as neutral dust particles. The plasmas relax then due to a collection ofelectrons and ions by dust particles. The free and collected electrons and ions are considered as a common subsystem described by the common whole distribution function. It is shown that this sub-sy...
