Basic Properties Of Fine Particle Dusty Plasmas

Beginning with typical values of physical parameters, basic properties of the system of fine particles (dusts) in plasmas are summarized from the viewpoint of statistical physics. Mutual interactions and one-body shadow potential for fine particles are derived, and, by analytic treatments and numerical solutions of drift-diffusion equations, it is shown that one of their most important characteristics is the large enhancement of the charge neutrality in fine particle clouds. This observation leads to simple models for the structures of fine particle clouds under both microgravity and usual gravity. Due to large magnitudes of their charges and relatively low temperatures, fine particles are often in the state of strong coupling, and some interesting phenomena possibly expected in their system are discussed with concrete examples. Also reviewed is the shell model, a useful framework to obtain microscopic structures in strongly coupled Coulomb and Coulomb-like systems with specific geometry.

In the field of plasma physics, plasmas (including charged fine particles) have been actively studied for more than 40 years, and special features of wave phenomena, self-organizations of the particles, potential formations, fluid-like motions of the particles, generations of fine particles in the plasmas, etc. have been investigated. Here, these plasmas are called “fine particle plasmas”, which are also called “dusty plasmas” and “complex plasmas”. This book intends to provide the reader with the recent progress of studies of fine particle plasmas from the viewpoints of wide and interdisciplinary directions, such as self-organized fine particles, Coulomb crystal formation, behaviors of fine particles, their stability, and syntheses of nano-sized particles in reactive plasmas. Further, the phenomena of dense grain particles and the effects of massive neutrinos in galaxy clustering are included.

Colloidal plasmas - a still emerging field of plasma physics - enable the study of basic plasma properties on a microscopic kinetic level and allow the visualization of collective plasma phenomena, like oscillations and waves. Moreover, a vast number of novel phenomena are found in these systems, ranging from Coulomb crystallization to new types of forces and waves. Last but not least, they shed a new light on various traditional aspects of plasma physics such as shielding or the mechanism of acoustic waves in plasmas, thus providing new insight into the basic foundations of plasma physics.These course-based and self-contained lecture notes provide a general introduction to this active and growing field to students and nonspecialists, requiring only basic prior knowledge in plasma physics. ​

Dusty or complex plasmas are plasmas containing solid or liquid charged particles referred to as dust. Naturally occurring in space, they are present in planetary rings and comet tails, as well as clouds found in the vicinity of artificial satellites and space stations. On a more earthly level, dusty plasmas are now being actively researched as dust plays a key role in technological plasma applications associated with etching technologies in microelectronics, as well as with production of thin films and nanoparticles. Complex and Dusty Plasmas: From Laboratory to Space provides a balanced and consistent picture of the current status of the field by covering new developments in experimental and theoretical research. Drawing from research performed across the earth and even beyond by an internationally diverse group of pioneering researchers, this book covers a wealth of topics. It delves into — Major types of complex plasmas in ground-based and microgravity experiments Properties of the magnetized, thermal, cryogenic, ultraviolet, nuclear-induced complex plasmas and plasmas with nonspherical particles Major forces acting on the particles and features of the particle dynamics in complex plasmas, as well as basic plasma-particle interactions, Recent research results on phase transitions between crystalline and liquid complex plasma states Astrophysical aspects of dusty plasmas and numerical simulation of their properties Dust as a source of contamination in many applications including reactors An important feature of this work is the detailed discussion of unique experimental and theoretical aspects of complex plasmas related to the investigations under microgravity conditions performed onboard Mir and ISS space stations. Much of what we know today would not be possible without cooperation between researchers of various nations, many of whom serve as key contributors to this book. Whether deepening their knowledge of things interstellar or developing new applications and products for use in manufacturing, energy, and communication or even fields yet dreamt of, these pages provide the knowledge, approaches, and insight that all researchers of complex plasmas need.

Introduction to Dusty Plasma Physics contains a detailed description of the occurrence of dusty plasmas in our Solar System, the Earth's mesosphere, and in laboratory discharges. The book illustrates numerous mechanisms for charging dust particles and provides studies of the grain dynamics under the influence of forces that are common in dusty plas

The study of dusty plasmas is now in a vigorous state of development. Dust and plasma coexist in a vast variety of cosmic environments and their research received a major boost in the early 80's with the Voyager spacecraft observations of peculiar features in the Saturnian ring system (e.g. the radial spokes) which could not be explained purely in gravitational terms. In addition, dust streams were measured by the Galileo spacecraft in the Jovian magnetosphere and charged dust in the earth's mesosphere was detected by a direct rocket experiment. Since then the area has greatly expanded with dedicated laboratory experiments verifying aspects of basic physics of charged dust grains in plasmas.These proceedings contain invited and poster papers which were presented by scientists active in the field from more than twenty countries. The material contains new aspects of collective interactions in dusty plasmas. For example, discoveries of dust-acoustic Mach cones, dust ion-acoustic shocks, great dust voids, vortex formation, dust crystallization under microgravity, coexistence of positive negative dust grains in the mesosphere and dust in tokamaks. The more theoretical and simulation studies focus on dynamical and structural properties and kinetic theories of strongly coupled dusty plasmas, as well as on self-organizations and structures, in addition to identifying forces (viz. wakefields, electrostatic and dipolar interactions etc.), which are responsible for charged dust grain attraction and phase transitions.The resulting book is a valuable, state-of-the-art review of the field of dusty plasma physics and will be welcomed by both researchers and graduate students who want to keep up to date in this rapidly growing field.
