This work gives an up-to-date account of the theory of dielectrics suitable for graduates and final-year undergraduates in physics, chemistry, electrical engineering and materials science. There is a concentration on the basic principles of the subject, without a detailed discussion of experimental data. The macroscopic behaviour of dielectric materials receives most attention; nevertheless an adequate introduction to the microscopic theory of dielectrics is given. The treatment is necessarily mathematical, but sufficient verbal explanations are given so that the physical ideas are not hidden beneath a morass of mathematical symbols. Detailed derivations of key results are provided in appendices, together with extensive lists of references and further general reading.
Since their rapid proliferation in the late 1960s and early 1970s, quadrupole mass spectrometers have had a profound impact across the physical sciences. Geometrically simple, yet behaviorally complex, these dynamic mass analyzers continue to facilitate remarkable breakthroughs in fields ranging from biochemical analysis to process control technology. Long regarded as the standard introduction to the field, Quadrupole Mass Spectrometry and Its Applications provides today's engineers and scientists with an authoritative, wide-ranging overview of the development and uses of quadrupoles. Beginning with the basic operating principles of quadrupole devices, the book moves from general explanations of the actions of radio-frequency fields to descriptions of their utilization in quadrupole mass filters, monopoles, three-dimensional quadrupole ion traps, and various time-of-flight spectrometers. A concluding series of chapters examines early applications of quadrupoles in atomic physics, gas chromatography, upper atmospheric research, medicine, and environmental studies. Superb writing from the field's foremost scientists along with the continued central role of quadrupoles in contemporary research make this volume as timely and relevant as ever.
Market: Those involved in the design and use of UHV component systems. Written 25 years ago, this book explains both the design and use of UHV systems and components, as well as the underlying physical principles on which the performance of the equipment depends. Because of its close association of these underlying physical principles with the practical problems inherent in UHV equipment, the book retains its value to this day.
Many books treat the physics of superconductivity; very few until now have covered the engineering. Superconducting Magnets meets this need, providing a complete theoretical basis for the quantitative engineering design of superconducting magnet systems, ranging from the small instrument magnets, now in everyday use as research tools, to the very large magnet systems used for work on thermonuclear fusion and magnetohydrodynamic power generation. Wilson devotes particular attention to the problem of stabilization, a crucial factor in the design process because of its bearing on the overall reliability of the completed system. He also describes the essential features of field and stress calculation, although in less detail, since they are covered extensively in other works. Other topics considered are measurement techniques, current supply (with emphasis on heat exchanging cryogenic current leads), superconducting materials, the major applications of superconducting magnets, and some practical techniques of magnet manufacture.

Engineers and scientists who develop and install electronic devices and circuits need to have a solid understanding of electromagnetic theory and the electromagnetic behavior of devices and circuits. In particular, they must be well-versed in electromagnetic compatibility, which minimizes and controls the side effects of interconnected electric devices. Designed to entice the practical engineer to explore some worthwhile mathematical methods, and to reorient the theoretical scientist to industrial applications, Electromagnetic Theory for Electromagnetic Compatibility Engineers is based on the author's courses taught in industrial settings. The book is a mathematically rigorous exposition of electromagnetic theory with applications in electromagnetic compatibility and high-speed digital design. The topics-ranging from Maxwell's theory and multi-conductor transmission line theory to S-matrix, antenna theory, and dielectric breakdown-were chosen because they have direct relevance to current electromagnetic compatibility problems encountered in the real world. With many worked examples and problem sets, the book relates the theory to practical experiences faced by practitioners. It is written both for physicists and mathematicians new to the field of electromagnetic compatibility and high-speed digital design, as well as established researchers in the field. It is also designed as an advanced undergraduate textbook for a course in electromagnetic theory.
This text provides the reader with a comprehensive understanding of the key ideas behind the physics of particle accelerators. Supported by a clear mathematical treatment and a range of calculations which develop a genuine feeling for the subject, it is a thorough introduction to the many aspects of accelerator physics.
This book provides a challenging and stimulating introduction to the contemporary topics of complexity and criticality, and explores their common basis of scale invariance, a central unifying theme of the book.Criticality refers to the behaviour of extended systems at a phase transition where scale invariance prevails. The many constituent microscopic parts bring about macroscopic phenomena that cannot be understood by considering a single part alone. The phenomenology of phase transitions is introduced by considering percolation, a simple model with a purely geometrical phase transition, thus enabling the reader to become intuitively familiar with concepts such as scale invariance and renormalisation. The Ising model is then introduced, which captures a thermodynamic phase transition from a disordered to an ordered system as the temperature is lowered in zero external field. By emphasising analogies between percolation and the Ising model, the reader's intuition of phase transitions is developed so that the underlying theoretical formalism may be appreciated fully. These equilibrium systems undergo a phase transition only if an external agent finely tunes certain external parameters to particular values.Besides fractals and phase transitions, there are many examples in Nature of the emergence of such complex behaviour in slowly driven non-equilibrium systems: earthquakes in seismic systems, avalanches in granular media and rainfall in the atmosphere. A class of non-equilibrium systems, not constrained by having to tune external parameters to obtain critical behaviour, is addressed in the framework of simple models, revealing that the repeated application of simple rules may spontaneously give rise to emergent complex behaviour not encoded in the rules themselves. The common basis of complexity and criticality is identified and applied to a range of non-equilibrium systems. Finally, the reader is invited to speculate whether self-organisation in non-equilibrium systems might be a unifying concept for disparate fields such as statistical mechanics, geophysics and atmospheric physics.Visit for animations for the models in the book (available for Windows and Linux), solutions to exercises, as well as a list with corrections.
Principles of Metal Refining and Recycling provides a self-contained introduction to the field of purification and recycling of metals. The scientific principles in the treatment of the various metals are the same. The importance of using a clean and properly alloyed metal is described in detail. The text covers thermodynamics, physical and transport properties, mixing, mass transfer and numerical models. It describes methods for removal of dissolved impurity elements, particles, and inclusions. It considers important aspects of the solidification process, remelting and adding of alloys. Recycling, future challenges and specific processes for each metal are discussed in detail. The book is a greatly extended update of the 1992 book Principles of Metal Refining by T. Abel Engh. It includes in particular the subjects of metal recycling, ferrous and non-ferrous metal refining, and metalloids like silicon.
Applied Computational Physics is a graduate-level text stressing three essential elements: advanced programming techniques, numerical analysis, and physics. The goal of the text is to provide students with essential computational skills that they will need in their careers, and to increase the confidence with which they write computer programs designed for their problem domain. The physics problems give them an opportunity to reinforce their programming skills, while the acquired programming skills augment their ability to solve physics problems. The C++ language is used throughout the text. Physics problems include Hamiltonian systems, chaotic systems, percolation, critical phenomena, few-body and multi-body quantum systems, quantum field theory, simulation of radiation transport, and data modeling. The book, the fruit of a collaboration between a theoretical physicist and an experimental physicist, covers a broad range of topics from both viewpoints. Examples, program libraries, and additional documentation can be found at the companion website. Hundreds of original problems reinforce programming skills and increase the ability to solve real-life physics problems at and beyond the graduate level.
This unique new book is a comprehensive review of the many current industrial applications of particle accelerators, written by experts in each of these fields. Readers will gain a broad understanding of the principles of these applications, the extent to which they are employed, and the accelerator technology utilized. The book also serves as a thorough introduction to these fields for non-experts and laymen. Due to the increased interest in industrial applications, there is a growing interest among accelerator physicists and many other scientists worldwide in understanding how accelerators are used in various applications. The government agencies that fund scientific research with accelerators are also seeking more information on the many commercial applications that have been or can be developed with the technology developments they are funding. Many industries are also doing more research on how they can improve their products or processes using particle beams
Albert Einstein may be best known as the wire-haired whacky physicist who gave us the theory of relativity, but that's just one facet of this genius's contribution to human knowledge and modern science. As Jozsef Illy expertly shows in this book, Einstein had an eminently practical side as well. As a youth, Einstein was an inveterate tinkerer in the electrical supply factory his father and uncle owned and operated. His first paid job was as a patent examiner. Later in life, Einstein contributed to many inventions, including refrigerators, microphones, and instruments for aviation. In published papers, Einstein often provided ways to test his theories and fundamental problems of the scientific community of his times. He delved deeply into a variety of technological innovations, most notably the gyrocompass, and consulted for industry in patent cases and on other legal matters. Einstein also provided explanations for common and mundane phenomena, such as the meandering of rivers. In these and other hands-on examples culled from the Einstein Papers, Illy demonstrates how Einstein enjoyed leaving the abstract world of theories to wrestle with the problems of everyday life. While we may like the idea of Einstein as a genius besotted by extra dimensions and too out-of-this-world to wear socks, The Practical Einstein gives ample evidence that this characterization is both incomplete and an unfair representation of a man who sought to explore the intricacies of nature, whether in theory or in practice.
This book addresses the question 'What is physics for?' Physics has provided many answers for mankind by extending his ability to see. Modern technology has enabled the power of physics to see into objects to be used in archaeology, medicine including therapy, geophysics, forensics and other< br> spheres important to the good of society. The book looks at the fundamental physics of the various methods and how they are used by technology. These methods are magnetic resonance, ionising radiation and sound. By taking a broad view over the whole field it encourages comparisons, but also< br> addresses questions of risk and benefit to society from a fundamental viewpoint. This textbook has developed from a course given to third year students at Oxford and is written so that it can be used coherently as a basis for shortened courses by omitting a number of chapters.
This work gives accounts of non-quantum optical phenomena and of instruments and technology based on them, at a level suitable for the last two years of an honours degree in physics and for graduates starting out. Topics covered include the conventional (diffraction, coherence, thin films, holography) and the less conventional (etendue, Gaussian beams, laser cavities, CD reader, confocal microscope) which belong in today's university courses, for example, to support laser physics. Even the conventional material has frequently been given a fresh presentation by giving a tidier-than-usual route through a calculation, or finding insightful connections with other parts of physics, or simply avoiding common errors. Problems offer opportunities for checking the reader's basic understanding, or for taking a careful route through reasoning, or for checking orders of magnitude. But most problems contain exploratory and critical material: investigating possible alternative approaches, asking searching questions about fundamentals, or solving apparent paradoxes.
Spatial change occurs whenever objects possess different spatial attributes at different times. This book discusses in detail the ingredients for a theory of qualitative spatial change: time, space, objects, their spatial attributes, and how these can vary. It provides a solid formal and theoretical basis for the computational modelling of spatial change.

Man versteht unter Technologie u. a. die Verarbeitung von Werk- stoffen zu betriebssicheren Produkten. Ein MaB fiir Betriebssicherheit ist z. B. die Lebensdauer, die ein Erzeugnis, das keiner Reparatur zuganglich ist, erreichen muB. Extreme Forderungen sind dabei urn so schwerer zu erfUllen, je vielgestaltiger das Produkt ist. Ein besonders komplexes Gebilde, an das hochste Anspriiche beziig- lich Lebensdauer gestellt werden, ist die Elektronenrohre. Sie ist fUr die Vakuumelektronik seit vielen Jahren von besonderer Bedeutung, und manche Pionierarbeit auf dem Weg zur modernen Technologie war an ihr zu leisten. Wenn sie oft nur noch als Dberbleibsel aus alten Zeiten angesehen wird, mag dies beziiglich der im taglichen Leben offen zutageliegenden Anwendung von Elektronik zutreffen. Doch dort, wo sie ihre Dienste mehr "im Verborgenen" zu verrichten hat, ist sie auch heute noch von "kriiftigem Leben" erfU11t. Wenn wir z. B. mit Dbersee telefonieren oder Fernsehbilder austauschen, geht dies weder bei den Sendestationen auf der Erde noch bei den Relais- stationen im Nachrichtensatelliten ohne Rohren abo Die auBeren und die inneren Formen haben sich vollig gewandelt, sie sind so kompliziert geworden, daB die Elektronenrohre immer noch zu den Produkten zahlt, deren erfolgreiche Herstellung fortschritt- lichste Technologie abverlangt. Damit ist sie ausgezeichnetes Objekt fUr die Erorterung eines Querschnitts durch dieses Gebiet. Man kann sicher sein, dabei viele niitzliche und verwertbare Hinweise fUr andere Gebiete der Vakuumelektronik zu geben. Der Zweck dieses Buches ist, gewonnene Erfahrungen von den Grund- lagen her in moglichst verstandlicher Form weiterzugeben.
