Dusty Plasma Liquids
The dusty plasma liquid formed by micro-meter sized particles negatively charged and suspended in a low pressure discharge background is a good candidate to study the generic spatio-temporal dynamical behaviors at the kinetic level through direct optical video-microscopy, because of the sub-mm interparticle spacing and the slow time scale. In this paper, starting from the basic picture of the a...
متن کاملA dusty plasma device for producing extended, steady state, magnetized, dusty plasma columns
We describe a rotating-drum dust-dispersal device, which we have used, in conjunction with an existing Q machine, to produce extended, steady state, magnetized plasma columns. The dusty plasma device (DPD) is to be used for the investigation of waves in dusty plasmas and of other plasma/dust aspects. The device is capable of generating dusty plasmas in which as much as -90% of the negative char...
متن کاملDusty Plasma Correlation Function Experiment
Dust particles immersed within a plasma environment, such as those in protostellar clouds, planetary rings or cometary environments, will acquire an electric charge. If the ratio of the inter-particle potential energy to the average kinetic energy is high enough the particles will form either a “liquid” structure with short-range ordering or a crystalline structure with long range ordering. Man...
متن کاملDNLS Solitons in Collisional Dusty Plasma
Alfven waves are possible sources of turbulence in the interstellar medium. These waves are responsible for the transport of angular momentum and energy in the accretion discs. Such waves have been studied for last several decades in space plasmas. Most of the space plasmas are dusty. They contain charged grains and coupling of the grains to the magnetic field determines the wave propagation in...
متن کاملProbe induced voids in a dusty plasma
Dusty plasmas are susceptible to the formation of a ‘‘void,’’ a centimeter-size region within the plasma that is free of dust particles. The boundary between the dust-free plasma ~void! and the dusty plasma is typically quite sharp. Praburam and Goree first reported the appearance of a spoke-shaped, dust-free region in a cloud of 100-nm carbon particles in a radio-frequency discharge formed bet...
