Dusty plasmas in laboratory and space applications
Department of Electrical and Computer Engineering
UC San Diego
Dusty plasmas are plasmas containing micron to sub-micron sized
solid particles, or dust grains, that are electrically charged.
Dust grains are present in many space and astrophysical
plasmas, such as planetary rings, comets, meteor trails,
noctilucent clouds, the interstellar medium, and star-forming regions.
Dust also occurs in laboratory plasmas,
such as those used for materials processing, the novel crystallized
dusty plasmas, and dusty plasma wave experiments.
In this talk, I will give an overview of some
recent theoretical work on dusty plasmas with applications to
diverse space and laboratory environments. Topics will include
applications of grain charging, the behavior of waves and instabilities,
and effects associated with strong dust coupling.
Applications to both space (e.g., meteor flight, space
shuttle exhaust plume, meteor trails) and the laboratory (e.g., dusty
plasma wave experiments, dust plasma crystals) will be discussed.
