Book Synopsis Space Plasma Simulation by : Jörg Büchner
Download or read book Space Plasma Simulation written by Jörg Büchner and published by Springer. This book was released on 2008-01-11 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is twofold: to provide an introduction for newcomers to state of the art computer simulation techniques in space plasma physics and an overview of current developments. Computer simulation has reached a stage where it can be a highly useful tool for guiding theory and for making predictions of space plasma phenomena, ranging from microscopic to global scales. The various articles are arranged, as much as possible, according to the - derlying simulation technique, starting with the technique that makes the least number of assumptions: a fully kinetic approach which solves the coupled set of Maxwell’s equations for the electromagnetic ?eld and the equations of motion for a very large number of charged particles (electrons and ions) in this ?eld. Clearly, this is also the computationally most demanding model. Therefore, even with present day high performance computers, it is the most restrictive in terms of the space and time domain and the range of particle parameters that can be covered by the simulation experiments. It still makes sense, therefore, to also use models, which due to their simp- fying assumptions, seem less realistic, although the e?ect of these assumptions on the outcome of the simulation experiments needs to be carefully assessed.

Available in PDF, EPUB and Kindle. Book excerpt: Intermittency is a defining characteristic of turbulence, and can be described as "the nonuni-form distriubtion of eddy formations in a stream" [55]. Spatial intermittency occurs when turbulent eddies are generated over a wide range of scales but do not fill the fluid volume, only irregu-lar sub-volumes [56]; this is associated with sharp gradients and coherent structures. Temporal intermittency occurs when fluctuations appear as "bursts" in time with varying durations and is characteristic of the turbulent cascade. Matthaeus and co-authors review the properties of spatial and temporal intermittency in both fluids and plasmas [57]. Intermittency is related to nonlinear phase-space structures called "holes" and "clumps" which were originally found in electrostatic turbulence simulations [58, 59]. Temporal intermittency has been associated with the inverse cas-cade of two-dimensional turbulence, as described in Section 1.3.
Download or read book Plasma Physics written by Alexander Piel and published by Springer Science & Business Media. This book was released on 2010-06-14 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an outgrowth of courses in plasma physics which I have taught at Kiel University for many years. During this time I have tried to convince my students that plasmas as different as gas dicharges, fusion plasmas and space plasmas can be described in a uni ed way by simple models. The challenge in teaching plasma physics is its apparent complexity. The wealth of plasma phenomena found in so diverse elds makes it quite different from atomic physics, where atomic structure, spectral lines and chemical binding can all be derived from a single equation—the Schrödinger equation. I positively accept the variety of plasmas and refrain from subdividing plasma physics into the traditional, but arti cially separated elds, of hot, cold and space plasmas. This is why I like to confront my students, and the readers of this book, with examples from so many elds. By this approach, I believe, they will be able to become discoverers who can see the commonality between a falling apple and planetary motion. As an experimentalist, I am convinced that plasma physics can be best understood from a bottom-up approach with many illustrating examples that give the students con dence in their understanding of plasma processes. The theoretical framework of plasma physics can then be introduced in several steps of re nement. In the end, the student (or reader) will see that there is something like the Schrödinger equation, namely the Vlasov-Maxwell model of plasmas, from which nearly all phenomena in collisionless plasmas can be derived.

Book Synopsis Characterizing Space Plasmas by : George K. Parks
Download or read book Characterizing Space Plasmas written by George K. Parks and published by Springer. This book was released on 2018-07-26 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: This didactic book uses a data-driven approach to connect measurements made by plasma instruments to the real world. This approach makes full use of the instruments’ capability and examines the data at the most detailed level an experiment can provide. Students using this approach will learn what instruments can measure, and working with real-world data will pave their way to models consistent with these observations. While conceived as a teaching tool, the book contains a considerable amount of new information. It emphasizes recent results, such as particle measurements made from the Cluster ion experiment, explores the consequences of new discoveries, and evaluates new trends or techniques in the field. At the same time, the author ensures that the physical concepts used to interpret the data are general and widely applicable. The topics included help readers understand basic problems fundamental to space plasma physics. Some are appearing for the first time in a space physics textbook. Others present different perspectives and interpretations of old problems and models that were previously considered incontestable. This book is essential reading for graduate students in space plasma physics, and a useful reference for the broader astrophysics community.
Book Synopsis Space Plasma Simulations by : M. Ashour-Abdalla
Download or read book Space Plasma Simulations written by M. Ashour-Abdalla and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergence over the past several years of space plasma simula tions as a distinct field of endeavor, rather than simply the somewhat startling offspring of plasma physics, computer simulations and space observations, has necessitated a concentrated effort at interdigitat ing its parent and component fields. After several years of working the benefits of a well-defined interactive community of those without working in the field, a group of those who had gained greatly from setting up joint research projects and other lines of communication, arranged to further these gains by setting up the First International School for Space Simulations, which was organized by Kyoto University and held in Kyoto, Japan in November 1982. Its unqualified success led to the organization of the second such School, this time by the University of California, Los Angeles, and held in Kapaa, Kauai, Hawaii. The Second International School for Space Simulations drew some 175 attendees from around the world; the distribution of attendees approached the targeted equal representation by established investi gators and graduate students/beginning investigators. This strong attendance by graduate students and beginning investigators was due to the generous support of a number of funding agencies from the United States and Japan as well as international scientific organizations.
Book Synopsis Measurement Techniques in Space Plasmas by : Robert F. Pfaff
Download or read book Measurement Techniques in Space Plasmas written by Robert F. Pfaff and published by American Geophysical Union. This book was released on 1998-02-04 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 102. Space plasma measurements are conducted in a hostile, remote environment. The art and science of measurements gathered in space depend therefore on unique instrument designs and fabrication methods to an extent perhaps unprecedented in experimental physics. In-situ measurement of space plasmas constitutes an expensive, unforgiving, and highly visible form of scientific endeavor.

Book Synopsis On the Extrapolation of Space-Simulation Beam-Plasma Investigations to Shuttle-Borne Applications by : E. P. Szuszczewicz
Download or read book On the Extrapolation of Space-Simulation Beam-Plasma Investigations to Shuttle-Borne Applications written by E. P. Szuszczewicz and published by . This book was released on 1982 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laboratory simulations of space plasma phenomena provide an important link in establishing broader perspectives of various plasma processes, in helping to understand spatially or temporally limited rocket and satellite observations, and in planning future spaceborne experiments. One such area has been the artificial injection of energetic electron beams in space which has transitioned from an early and somewhat confused set of rocket data through a relatively intensive program of laboratory based space simulations, to an ambitious program which exploits the Shuttle as a readily accessible laboratory in space. While accumulated information points to a considerably improved understanding of beam plasma parameters which define single particle behavior on the one hand and collective beam plasma properties on the other, the extrapolation of these results to Shuttle borne applications is met with a number of constraints. Focusing on the transition from single particle behavior to the collective nonlinear interactions in the beam plasma discharge, this paper provides a comparative analysis on aspects involving Shuttle unique environmental effects. Emphasis is placed on Shuttle potentials and associated sheaths, ambient plasma and neutral density effects including relative spacecraft motion, pulsed versus dc gun operation, and beam plasma discharge criteria in general.

Available in PDF, EPUB and Kindle. Book excerpt: Computer simulation is now widely recognized as a powerful tool and useful method at the current stage of research in space plasma physics. The expected role of computer simulation is to bridge the existing gap between theories and experiments/observations and to give a profound physical insight into highly tangled and nonlinearly coupled space plasma phenomena. One of the goals of space plasma physics in 1980's and 1990's is to elucidate the quantitative causal relationships of global and local energy flows in space plasma environment and establish the space plasma physics via cooperative studies among three important elements of observations, theories and computer simulations. Based on such recognition, Dr. M. Ashour-Abdalla (UCLA/USA), Dr. R. Gendrin (CNET/FRANCE) and both of us met together at the 20th General Assembly of URSI at Washington D. C. in 1981 to discuss what we should do and what we could do, reaching a conclusion that it is time to establish an International School of Space Simulations (ISSS). The objectives of the ISSS thus organized are firstly to educate and stimulate graduate students and young sCientists, secondly to exchange information on updated simulation techniques and thirdly to have mutual discussions among observational, theoretical and simulational scientists in the field of space physics. The first ISSS were organized by Prof. P. Coleman, Prof. T. Obayashi, Dr. H. Okuda in addition to the above four members. The first ISSS was held at Kansai Seminar House in Kyoto from Nov. I to Nov. 12, 1982.

This book was released on 2012-12-06 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the lectures presented at the International Workshop on Relation between Laboratory and Space Plasmas held at Gakushi-Kaikan (University Alumni Association) Kanda in Tokyo, Japan on 14 - 15 April, 1980. Its aim was to bring together laboratory, fusion and space plasma physicists and to highlight the communality of basic plasma phenomena, similarities and differences observed in the laboratory and in space, thus exchanging information tnd views on new ideas to link both areas. Although similar type of conferences were held in Europe and recently in the States, this is the first time we have had in Japan for such an international meeting, which may be regarded as an extended version of our national Workshop held twice at the Institute of Plasma Physics of Japan (IPPJ) in 1976 and in 1977 (IPPJ Research Report No. 286 and No. 365). The Workshop consisted of seven regular sessions and one special session with approximately ninety participants from allover the world. Thirty-six papers, invited and contributed, were presented, nine from U. S. A., three from U. S. S. R., two of each from Germany, France, India, one of each from Sweden, Canada, Belgium and fifteen from Japan. The topics covered were: (1) The Critical Velocity (2) Beam Plasma Discharges and Interactions (3) Double Layers and Shocks (4) Instabilities in the Equatorial and Auroral Electrojets (5) Turbulent and Anomalous Plasmas (6) Plasma Irregularities (7) Solar Plasma Phenomena (8) Active Experiments in Space Plasmas and Their Simulation in the Laboratory.

Download or read book Techniques for the Simulation of the Space Plasma Environment written by Ward D. Halverson and published by . This book was released on 1980 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of space plasmas with distributed spectra of particle energies can be simulated in the laboratory by combinations of monoenergetic electron and ion beams. The energy and current density of beams are calculated to match various moments of the velocity distribution function of distributed spectra. Analytical solutions have been found for one- and two-beam matching, respectively, of two- and four-velocity moments of arbitrary distribution functions. A three-energy solution which matches six moments of a Maxwellian distribution is presented, as well as multiple-beam solutions for matching two-Maxwellian distributions. (Author).
