Описание: This book presents the first comprehensive account of the properties of plasma loops, the fundamental structural elements of the solar corona. Plasma loops cover a wide range of sizes, and range in temperature from tens of thousands to millions of degrees. They not only define the structure of individual active regions but connect different active regions - even across the solar equator. Loops also play an integral and decisive role in the enormous solar explosions called flares. Over recent years a wealth of space and ground-based observations of loops has been obtained in various widely-spaced regions of the electromagnetic spectrum. In this book the authors have selected the best observational material from the literature on which to base a detailed account of the properties of flare and non-flare loops. The book also explores the larger implications of the loop structures in our understanding of solar and stellar coronae. The text is enhanced by a large number of illustrations and unique and beautiful photographs obtained from the ground and from space.
Описание: Features material on electronic signal creation, amplification and shaping. This title discusses such topics as the basics of gas ionization, electronic drift and signal creation and also discusses the fundamental limits of accuracy and the issue of particle identification.
Описание: This book presents a synthesis of what we learned about particle acceleration and kinematics from recent solar flare observations with the Yohkoh, SoHO, TRACE, CGRO spacecraft and radio instruments over the last decade. It deals with the topology of magnetic reconnection regions, discusses the geometry, small-scale dynamics, and electromagnetic fields of acceleration region in solar flares, provides a systematic description of the relativistic kinematics of particle acceleration, propagation, time-of-flight measurements, particle trapping, precipitation, and the resulting emissions in gamma rays, hard X-rays, and radio wavelengths. It is the first monograph on these solar flare topics, written for the level of graduate students and researchers in the field of solar physics, astrophysics, and magnetospheric physics.
Описание: Beam emittance growth, halo formation and chaotic particle motion are all key aspects in the design of particle accelerators with space-charge-dominated
beams. This title provides a description of these beams, and is suitable for professionals, graduates and students working in this field.
Описание: This book is composed of 11 articles written by senior scientists in the field of laser plasma acceleration and radiation. The papers were presented at the 1st Asian Summer School on Laser Plasma Acceleration and Radiation, held August 7-11, 2006 in Beijing China. The field is a fast-developing new frontier in physics. The lectures presented at the Summer School covered a broad spectra ranging from particle acceleration process in plasma driven by lasers; laser accelerated beam characteristics both for electrons and ions; superstrong electromagnetic fields and their applications; novel radiations by high harmonics; X-ray laser sources; ultra-intense radiation by relativistic engineering; related astrophysical phenomena, and so on. The readers of these proceedings will gain a relatively complete picture on laser-plasma acceleration and radiation and their applications.

Описание: Intended for graduate students and astronomers seeking an introduction to coronal physics, this textbook strikes a balance between the observational and theoretical aspects of the subject. This second edition takes into account the major observational and theoretical developments of recent years to provide an up-to-date treatment of our understanding of the solar corona. After reviewing the latest observations of the solar corona, the authors explain how the studies have advanced and shaped our understanding of coronal physics. The textbook introduces a wide variety of exciting physics, including dynamo theory and magnetohydrodynamics, and shows how the transient effects of the solar cycle affect space weather. Each subject area is introduced using basic physics, and refers readers to fundamental papers on the topic, key new studies in each area, and extensive discussions in recent review articles.
Описание: Photovoltaics, the direct conversion of sunlight to electricity, is now the fastest growing technology for electricity generation. Present "first generation" products use the same silicon wafers as in microelectronics. "Second generation" thin-films, now entering the market, have the potential to greatly improve the economics by eliminating material costs. Martin Green, one of the worlds foremost photovoltaic researchers, argues in this book that "second generation" photovoltaics will eventually reach its own material cost constraints, engendering a "third generation" of high performance thin-films. The book explores, self-consistently, the energy conversion potential of advanced approaches for improving photovoltaic performance and outlines possible implementation paths.
Описание: The book consists of four Chapters. Chapter 1 shortly describes main properties of space plasmas and primary CR, different types of CR interactions with space plasmas components (matter, photons, and frozen in magnetic fields). Chapter 2 considers the problem of CR propagation in space plasmas described by the kinetic equation and different types of diffusion approximations (diffusion in momentum space and in pitch-angle space, anisotropic diffusion, anomaly CR diffusion and compound diffusion, the influence of magnetic clouds on CR propagation, non-diffusive CR particle pulse transport).Chapter 3 is devoted to CR non-linear effects in space plasmas caused by CR pressure and CR kinetic stream instabilities with the generation of AlfvГЁn turbulence (these effects are important in galaxies, in the Heliosphere, in CR and gamma-ray sources and in the processes of CR acceleration). In Chapter 4 different processes of CR acceleration in space plasmas are considered: the development of the Fermi statistical mechanism, acceleration in the turbulent plasma, Alfven mechanism of magnetic pumping, induction mechanisms, acceleration during magnetic collapse and compression, cumulative acceleration mechanism near the zero lines of a magnetic field, acceleration in shear flows, shock-wave diffusion (regular) acceleration. The book ends with a list providing more than 1,300 full references, a discussion on future developments and unsolved problems, as well as Object and Author indexes. This book will be useful for experts and students in CR research, Astrophysics and Geophysics, and in Space Physics.
Описание: An outgrowth of a workshop held by the Community of European Solar Radio Astronomers (CESRA), this volume collects reviews on current research and perspectives on the variable solar corona: high-energy particles, large-scale disturbances such as mass ejections and waves, and radio diagnostics of the coronal plasma. Multiwavelength observations of the Sun with radio instruments and recent space missions are drawn on extensively, as well as input from neighbouring fields e.g. solar wind, Earth's bow shock. Recent developments are discussed alongside key developments in this rapidly evolving field.

Описание: Offers an introduction to the subject of solar physics, based on spacecraft observations. This book introduces the solar corona and sets it in the context of basic plasma physics before moving on to discuss plasma instabilities and plasma heating processes. It also describes phenomena such as solar flares and coronal mass ejections.
Описание: This thoroughly revised textbook is a basic introduction to plasma phenomena in solar and stellar coronae emphasizing non-MHD aspects. The natural way in which the author unifies observations and theory gives a wide perspective to the subject. An important feature is the lucidly written presentation of the fundamentals of plasma physics. The basic theory thus developed is then extended to some exemplary and important observations of coronal dynamics, such as coronal currents, particle acceleration, propagation of particle beams, and shocks. The book has grown from teaching introductory courses on plasma astrophysics at the Swiss Federal Institute of Technology (ETH). It addresses advanced undergraduates and first-year graduate students without a background in plasma physics. It will also be of interest to more senior research workers involved in coronal physics of the Sun and other stars, solar/stellar winds, and various other fields of plasma astrophysics.
