Dust is ubiquitous in the universe and responsible for stellar and planetary formation. Virtually all previous studies have considered the dust particulates to be a charge neutral component. Satellite missions such as Voyager revealed the extent to which charged dust plays a role in astrophysics. In most areas dust exists in the presence of a dilute plasma. In such a plasma environment the dust becomes charged to a variety of processes (eg photo-ionisation, collisions with electrons and ions, thermionic emission etc). Closer to home in the Earth's mesosphere, rocket measurements and radar observations conclusively demonstrate the importance of charged dust in forming complex structures responsible for Polar Mesospheric Summer Echoes. This book is the outcome of a periodic collaboration between a small group of scientists meeting twice a year at the International Space Science Institute (ISSI) in Bern, Switzerland over a period of three years. The book begins with a description of the fundamental physical processes which characterise dusty plasmas. Starting with charging and shielding of isolated dust particles in a plasma environment, the review progresses to non-linear dust dynamics of spherical and irregular dust. In an ensemble of a dust plasma system collective processes begin to manifest themselves in the form of new wave modes and instabilities which play an important role in the collective behaviour displayed in space and astrophysical environment. Finally more exotic topics, such as the Ising model for irregular dust grain alignment, classical Casimir forces and chargeons are explored.

In this volume a thorough review is given of waves in dusty plasmas, a fascinating new domain combining plasmas and charged dust, two omnipresent ingredients of the Universe. Spokes and braids observed in the rings of Saturn cannot be explained by gravitation alone, but need the presence of charged dust. Other examples abound, as in zodiacal light, noctilucent clouds, comets and molecular clouds. After discussing charging mechanisms, supported by exciting new experiments, and space observations, the book describes extensions of known plasma modes covering the low frequencies typical for charged dust. Mixing detailed theoretical steps with summaries of expert contributions, a systematic multi-species treatment puts the literature in perspective, suitable also for newcomers. Typical complications like fluctuating dust charges, self-gravitational effects, and size distributions are dealt with, before ending with an outlook to future work and open questions. In this way, experts as well as interested newcomers will find a reliable guide, not just a compendium.

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.

I have been asked by Professor Kikuchi to write a foreword for this interesting book on Dusty Plasmas and other electrical phenomena. This was a somewhat daunting task due to the wide range of topics covered. In what follows I have attempted to summarize most of these topics; for this purpose I have divided them into four groups, namely (a) Dusty Plasmas, (b) The Electrical Environment, (c) Lightning and (d) The Noise Environment. I hope that I have succeeded. in indicating that each section contains much that is of great interest. It is perhaps unnecessary for me to point out that the book contains subjects which are at an exciting and important stage in their development. (a) Dusty Plasmas The subject of dusty plasmas is one of great interest. Dust particles in interplanetary space, within comets, in inter-stellar space and at ever greater distances will in general be charged. The plasma environment will ensure this, bombarding electrons will charge up the particle until it assumes a "floating potential," although time variation can occur. Ultra violet radiation can cause photoemission and in certain cases field emission is a possibility. The motion of the particles will be determined by electric and magnetic fields together with gravity. If the density of charged grains becomes sufficiently high the grains will interact with each other and collective behaviour will ensue. This newly evolving subject entails the study of all kinds of plasma waves.

Computer simulation of systems has become an important tool in scientific research and engineering design, including the simulation of systems through the motion of their constituent particles. Important examples of this are the motion of stars in galaxies, ions in hot gas plasmas, electrons in semiconductor devices, and atoms in solids and liquids. The behavior of the system is studied by programming into the computer a model of the system and then performing experiments with this model. New scientific insight is obtained by observing such computer experiments, often for controlled conditions that are not accessible in the laboratory. Computer Simulation using Particles deals with the simulation of systems by following the motion of their constituent particles. This book provides an introduction to simulation using particles based on the NGP, CIC, and P3M algorithms and the programming principles that assist with the preparations of large simulation programs based on the OLYMPUS methodology. It also includes case study examples in the fields of astrophysics, plasmas, semiconductors, and ionic solids as well as more detailed mathematical treatment of the models, such as their errors, dispersion, and optimization. This resource will help you understand how engineering design can be assisted by the ability to predict performance using the computer model before embarking on costly and time-consuming manufacture.

Complex plasmas are dusty plasmas in which the density and electric charges of the dust grains are sufficiently high to induce long-range grain-grain interactions, as well as strong absorption of charged-plasma components. Together with the sources replenishing the plasma such systems form a highly dissipative thermodynamically open system that exhibits many features of collective behaviour generally found in complex systems. Most notably among them are self-organized patterns such as plasma crystals, plasma clusters, dust stars and further spectacular new structures. Beyond their intrinsic scientific interest, the study of complex plasmas grows in importance in a great variety of fields, ranging from space-plasma sciences to applied fields such as plasma processing, thin-film deposition and even the production of computer chips by plasma etching, in which strongly interacting clouds of complex plasmas can cause major contamination of the final product. Intended as first introductory but comprehensive survey of this rapidly emerging field, the present book addresses postgraduate students as well as specialist and nonspecialist researchers with a general background in either plasma physics, space sciences or the physics of complex systems.

The diverse and often surprising new facts about planetary rings and comet environments that were reported by the interplanetary missions oflate 1970s - 1980s stimulated investigations of the so-called dusty plasma. The number of scientific papers on the subject that have been published since is quite impressive. Recently, a few surveys and special journal issues have appeared. Time has come to integrate some of the knowledge in a book. Apparently, this is the first monograph on dusty and self-gravitational plasmas. While the circle of pertinent problems is rather clearly defined, not all of them are equally represented here. The authors have concentrated on cooperative phenomena (Le. waves and instabilities) in the dusty plasma and the effects of self-gravitation. At the same time, in an attempt to present the vast material consistently, we have included such topics as electrostatics of the dusty plasma and gravitoelectrodynamics of individual charged particles. Also mentioned are astrophysical implications, mostly concerning planetary rings. We hope that the book shall be of interest and value both to specialists and those (astro )physicists who have just discovered this area of plasma physics. We are thankful to many scientists actively working in the field of dusty plasma physics who have generously let us become acquainted with their results, sometimes prior to publication of their own papers: U. de Angelis, N. D'Angelo, o. Havnes, A. Mendis, M. Rosenberg, P. Shukla, F. Verheest, and E. Wollman.

Complex plasmas differ from traditional plasmas in many ways: these are low-temperature high pressure systems containing nanometer to micrometer size particles which may be highly charged and strongly interacting. The particles may be chemically reacting or be in contact with solid surfaces, and the electrons may show quantum behaviour. These interesting properties have led to many applications of complex plasmas in technology, medicine and science. Yet complex plasmas are extremely complicated, both experimentally and theoretically, and require a variety of new approaches which go beyond standard plasma physics courses. This book fills this gap presenting an introduction to theory, experiment and computer simulation in this field. Based on tutorial lectures at a very successful recent Summer Institute, the presentation is ideally suited for graduate students, plasma physicists and experienced undergraduates.
