Available in PDF, EPUB and Kindle. Book excerpt: Planetary Volcanism across the Solar System compares and contrasts the vast array of planetary bodies in the Solar System, including Earth. The wealth of spacecraft data for almost all major solid-surface bodies in the Solar System indicate that volcanism has been a dominant mechanism in shaping the landscapes of these bodies. The book addresses key questions surrounding our understanding of planetary volcanism, such as how to integrate the data into a coherent view of how volcanic activity arises, how this mechanism shapes planets, which volcanic landforms are ubiquitous throughout the Solar System, and which are unique. By placing a singular emphasis on comparing volcanic processes and landforms on all relevant Solar System bodies, and with the explicit objective of providing a systems-level understanding of this widespread phenomenon, users will find an up-to-date, accessible and comprehensive discussion of the major volcanic processes and landforms that shape and drive the evolution of planets, moons and smaller bodies.

This book was released on 1967 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An anisotropic electron velocity distribution was produced in a magnetized plasma by means of an intense AC electric field near the cyclotron resonance. Unstable electrostatic waves associated with such a distribution were investigated theoretically and confirmed experimentally using the combination scattering technique. In particular, waves near the second harmonic of the electron motion imposed by the AC field were studied in detail. Their dependence on the plasma density was measured and very good agreement with the theory was obtained. Experimental observations showed that the waves were stimulated by the external AC power at least in low plasma densities. At higher plasma densities there was evidence of self-excitation. The growth rates were measured. Cyclotron harmonic electrostatic waves associated with the Maxwellian distribution, (in the absence of the AC field), were observed by means of the same technique. They were excited near the second harmonic by an extraordinary electromagnetic wave which was weakly coupled to the plasma and therefore did not perturb the thermal distribution. Qualitative agreement with the theory and other related experiments was obtained in this case. (Author).

Download or read book Electromagnetic Waves For Thermonuclear Fusion Research written by Ernesto Mazzucato and published by World Scientific. This book was released on 2014-04-02 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science of magnetically confined plasmas covers the entire spectrum of physics from classical and relativistic electrodynamics to quantum mechanics. During the last sixty years of research, our initial primitive understanding of plasma physics has made impressive progress thanks to a variety of experiments — from tabletop devices with plasma temperatures of a few thousands of degrees and confinement times of less than 100 microseconds, to large tokamaks with plasma temperatures of up to five hundred million degrees and confinement times approaching one second. We discovered that plasma confinement is impaired by a variety of instabilities leading to turbulent processes with scales ranging from the plasma size to a few millimeters. Understanding these phenomena, which have slowed down progress towards a fusion reactor, requires the use of very sophisticated diagnostic tools, many of which employ electromagnetic waves.The primary objective of this book is to discuss the fundamental physics upon which the application of electromagnetic waves to the study of magnetically confined plasmas is based.

Download or read book Magnetohydrodynamics of Plasma Relaxation written by S. Ortolani and published by World Scientific. This book was released on 1993 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a concise description of the phenomenon of plasma relaxation from the point of view of resistive magnetohydrodynamic (MHD) theory. Magnetized plasmas relax when they seek their natural state of lowest energy subject to certain topological constraints imposed by the magnetic field. Relaxation may be fast and dynamic or slow and gradual depending on the external environment in which the magnetoplasma system evolves. Relaxation occurs throughout the universe and may describe such diverse phenomena as dynamos, solar flares, and the operation of magnetic fusion energy experiments. This book concentrates on the dynamic, rather than variational aspects of relaxation. While the processes described are general, the book focuses on the reversed-field pinch experiment as a paradigm for plasma relaxation and dynamo action. Examples from other branches of plasma physics are also discussed. The authors draw upon their extensive experience in numerical and experimental studies of relaxation.

Available in PDF, EPUB and Kindle. Book excerpt: The essential introduction to magnetic reconnection—written by a leading pioneer of the field Plasmas comprise more than 99 percent of the visible universe; and, wherever plasmas are, magnetic reconnection occurs. In this common yet incompletely understood physical process, oppositely directed magnetic fields in a plasma meet, break, and then reconnect, converting the huge amounts of energy stored in magnetic fields into kinetic and thermal energy. In Magnetic Reconnection, Masaaki Yamada offers an illuminating synthesis of modern research and advances on this important topic. Magnetic reconnection produces such phenomena as solar flares and the northern lights, and occurs in nuclear fusion devices. A better understanding of this crucial cosmic activity is essential to comprehending the universe and varied technological applications, such as satellite communications. Most of our knowledge of magnetic reconnection comes from theoretical and computational models and laboratory experiments, but space missions launched in recent years have added up-close observation and measurements to researchers’ tools. Describing the fundamental physics of magnetic reconnection, Yamada links the theory with the latest results from laboratory experiments and space-based observations, including the Magnetic Reconnection Experiment (MRX) and the Magnetospheric Multiscale (MMS) Mission. He concludes by considering outstanding problems and laying out a road map for future research. Aimed at advanced graduate students and researchers in plasma astrophysics, solar physics, and space physics, Magnetic Reconnection provides cutting-edge information on a vital area of scientific investigation.

This book was released on 2019-06-28 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present research studies the fundamental physics occurring during the magnetic flux and magnetized plasma compression by plasma implosion. This subject is relevant to numerous studies in laboratory and space plasmas. Recently, it has attracted particular interest due to the advances in producing high-energy-density plasmas in fusion-oriented experiments, based on the approach of magnetized plasma compression. The studied configuration consists of a cylindrical gas-puff shell with pre-embedded axial magnetic field that pre-fills the anode-cathode gap. Subsequently, axial pulsed current is driven through the plasma generating an azimuthal magnetic field that compresses the plasma and the axial magnetic field embedded in it. A key parameter for the understanding of the physics occurring during the magnetized plasma compression is the evolution and distribution of the axial and azimuthal magnetic fields. Here, for the first time ever, both fields are measured simultaneously employing non-invasive spectroscopic methods that are based on the polarization properties of the Zeeman effect. These measurements reveal unexpected results of the current distribution and the nature of the equilibrium between the axial and azimuthal fields. These observations show that a large part of the current does not flow in the imploding plasma, rather it flows through a low-density plasma residing at large radii. The development of a force-free current configuration is suggested to explain this phenomenon. Previously unpredicted observations in higher-power imploding-magnetized-plasma experiments, including recent unexplained structures observed in the Magnetized Liner Inertial Fusion experiment, may be connected to the present discovery.

Download or read book On the Edge of Magnetic Fusion Devices written by Sergei Krasheninnikov and published by Springer Nature. This book was released on 2020-09-07 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the current state of understanding concerning edge plasma, which bridges hot fusion plasma, with a temperature of roughly one million degrees Kelvin with plasma-facing materials, which have melting points of only a few thousand degrees Kelvin. In a fact, edge plasma is one of the keys to solution for harnessing fusion energy in magnetic fusion devices. The physics governing the processes at work in the edge plasma involves classical and anomalous transport of multispecies plasma, neutral gas dynamics, atomic physics effects, radiation transport, plasma-material interactions, and even the transport of plasma species within the plasma-facing materials. The book starts with simple physical models, then moves on to rigorous theoretical considerations and state-of-the-art simulation tools that are capable of capturing the most important features of the edge plasma phenomena. The authors compare the conclusions arising from the theoretical and computational analysis with the available experimental data. They also discuss the remaining gaps in their models and make projections for phenomena related to edge plasma in magnetic fusion reactors.

Download or read book A Theoretical Investigation of Electromagnetic Waves Obliquely Incident Upon a Plasma Slab written by Calvin T. Swift and published by . This book was released on 1970 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of an electromagnetic wave obliquely incident upon a plasma slab is considered as a boundary-value problem by use of a self-consistent solution of the coupled linearized Vlasov and Maxwell equations. Power reflection, transmission, and absorption coefficients are derived under the assumption that all particles undergo specular reflection at the surfaces of the plasma slab. Although the analysis is valid for arbitrary slab thickness, computational results are presented for slabs which are thin when compared with a wavelength. The results show that a series of resonances occur which are attributed to the finite temperature of the plasma. The results further show that the resonances are Landau damped as the thermal velocity of the plasma electrons increases. It is shown that similar resonances can be predicted from the coupled linearized hydrodynamic Maxwell equations; however, as is well known, such a model does not predict Landau damping. The effects of a finite collision frequency are then included by means of a simple Bhatnagar-Gross-Krook (BGK) collision term. The numerical computations vividly indicate that the resonances undergo severe damping for extremely small ratios of the collision frequency to the signal frequency. Finally, the plasma capacitor problem is considered, and the results indicate that the longitudinal resonances have characteristics very similar to those of the plane-wave resonances.
