This book provides a comprehensive overview of the operating principles and technology of electron lenses in supercolliders. Electron lenses are a novel instrument for high energy particle accelerators, particularly for the energy-frontier superconducting hadron colliders, including the Tevatron, RHIC, LHC and future very large hadron colliders. After reviewing the issues surrounding beam dynamics in supercolliders, the book offers an introduction to the electron lens method and its application. Further chapters describe the technology behind the electron lenses which have recently been proposed, built and employed for compensation of beam-beam effects and for collimation of high-energy high-intensity beams, for compensation of space-charge effects and several other applications in accelerators. The book will be an invaluable resource for those involved in the design, construction and operation of the next generation of hadron colliders.
These are the proceedings of the 141h Winter \Vorkshop on Nuclear Dynamics, the latest of a serif'S of workshops that was started in 1~)78. This series has grown into a tradition. bringing together experimental and theoretical expertise from all areas of the study of nudear dynamics. Following tllf' tradition of the Workshop the program covered a broad range of topics aerof'S a large energy range. At the low energy end llluitifragmentation and its relationship to the nuclear liquid to gas phase transition was disclIssf'd in grf'at df'- tail. New pxpf'rimental data, refined analysis techniques, and new theoretical effort have lead to considerable progress. In the AGS energy range we see the emergence of systematic data that contribute to our understanding of the reaction dynamics. The workshop also showf'd that at CERN energies Itadronic data become much more precise and complet.e and a renewed emphasis on basic hadronic processes and hadronic struc- ture as a precondition to understand the initial conditions and a basis for systematic comparisons.

This revised and extended edition of the book Fields, Symmetries, and Quarks, originally published by McGraw-Hill Book Company, Hamburg, 1989, contains a new chapter on electroweak interactions which has also grown out of lectures that I have given in the meantime. In addition, a number of changes, mainly in the metric used, in the discussion of the theory of strong interactions, QCD, and in the chapter on hadron physics, have been made and errors have been corrected. The motivation for this book, however, is still the same as it was 10 years ago: This is a book on quantum field theory and our present understanding of leptons and hadrons for advanced students and the non-specialists and, in particular, the experimentalists working on problems of nuclear and hadron physics. I am grateful to Dr. S. Leupold for a very careful reading of the revised manuscript, many corrections, and helpful suggestions and to C. Traxler for producing the figures and for constructive discussions.
The primary objective of the book on "Contemporary Topics in Medium Energy Physics" is to help the reader in exploring important frontier research, as of the year of 1992, in the area of medium energy physics. The book is the result of the multi-pronged efforts by the authors who were invited to speak at the Second German Chinese Symposium on "Medium Energy Physics" (September 7-10, 1992, Bochum, Germany). The premise of the meeting is to investigate primarily how quantum chromo dynamics (QCD), the candidate theory of strong interactions, manifests itself in high energy and nuclear physics. This book is divided into four parts: (i) field-theoretic treatments in QCD; (ii) effective chirally symmetric models and QCD; (iii) electroweak physics in general; and (iv) topological solutions. The focus is more on exposition of new ideas, rather than a comprehensive review of the current status, concerning these subjects, as of the year of 1992. As there are many distinctly different research areas in contemporary intermediate energy physics, we could only choose a few topics of current interest, especially those which are related, directly or indirectly, to the structural studies of the nucleon (proton or neutron). Fortunately, there are in recent years merging trends in these studies: There is a call for an alternative, and more efficient, method to handle problems related to strong interactions (as described by QCD). This is the focus of the papers included in Part I."
The author develops a novel analysis method for QCD sum rules (QCDSR) by applying the maximum entropy method (MEM) to arrive at an analysis with less artificial assumptions than previously held. This is a first-time accomplishment in the field. In this thesis, a reformed MEM for QCDSR is formalized and is applied to the sum rules of several channels: the light-quark meson in the vector channel, the light-quark baryon channel with spin and isospin 1/2, and several quarkonium channels at both zero and finite temperatures. This novel technique of combining QCDSR with MEM is applied to the study of quarkonium in hot matter, which is an important probe of the quark-gluon plasma currently being created in heavy-ion collision experiments at RHIC and LHC.
Recent books have raised the public consciousness about the dangers
of global warming and climate change. This book is intended to
convey the message that there is a solution. The solution is the
rapid development of hydrogen fusion energy. This energy source is
inexhaustible and, although achieving fusion energy is difficult,
the progress made in the past two decades has been remarkable. The
physics issues are now understood well enough that serious
engineering can begin.The book starts with a summary of climate
change and energy sources, trying to give a concise, clear,
impartial picture of the facts, separate from conjecture and
sensationalism. Controlled fusion -- the difficult problems and
ingenious solutions -- is then explained using many new
concepts.The bottom line -- what has yet to be done, how long it
will take, and how much it will cost -- may surprise you.
Market: Scientists and students involved in thermonuclear fusion research. Thermonuclear fusion research using the confinement device tokamak represents one of the most prominent science projects in the second half of the 20th century. International Tokamak Community is now committing significant effort and funds to experiments with burning plasma, hot and dense enough to produce significant nuclear fusion reactions. The methods used to enhance tokamak performance have a profound and immediate effect on machine design. This book provides an up-to-date account of research in tokamak fusion and puts forward innovative ideas in confinement physics.
This volume contains the invited contributions to the NATO Advanced Research Workshop on Integrable Quantum Field Theories held at the Villa Olmo, Como, Italy, September 14-18, 1992. About 70 researchers from all over world gathered at this in- terdisciplinary workshop, which turned out to be timely and very stimulating. We are grateful to the institutions that made it possible: the NATO Scientific Affairs Divi- sion, the Istituto Nazionale di Fisica Nucleare and the Scuola Internazionale Superiore di Studi Avanzati for financial support, and the Centro A.Volta for hospitality. In the past decades integrability was mostly explored in the framework of mathe- matical physics. However, in the last few years it has become a prominent subject in many domains of theoretical physics: two dimensional statistical mechanical models, two-dimensional conformal field theories and their perturbations, matrix models of two-dimensional gravity. This trend has been confirmed by the workshop: progress has been reported in all of the above topics both from physicists and mathematicians. One can recognize three broad groups of subjects: 1) 2D lattice models and off-critical solvable models, 2) Kac-Moody algebras and their role in integrable theories, 3) matrix models of string theory and their relation with topological and integrable field theories.
Addressing graduate students and researchers, this book gives a very detailed theoretical and computational description of multiple scattering in solid matter. Particular emphasis is placed on solids with reduced dimensions, on full potential approaches and on relativistic treatments. For the first time approaches such as the screened Korringa-Kohn-Rostoker method are reviewed, considering all formal steps such as single-site scattering, structure constants and screening transformations, and also the numerical point of view. Furthermore, a very general approach is presented for solving the Poisson equation, needed within density functional theory in order to achieve self-consistency. Special chapters are devoted to the Coherent Potential Approximation and to the Embedded Cluster Method, used, for example, for describing nanostructured matter in real space. In a final chapter, physical properties related to the (single-particle) Green's function, such as magnetic anisotropies, interlayer exchange coupling, electric and magneto-optical transport and spin-waves, serve to illustrate the usefulness of the methods described.
This monograph incorporates the general physical concepts that form the foundation of the phenomenon of giant resonances and a review of the study of nuclear structure at finite temperature. It includes the study of the g-decay of giant resonances from compound nuclei (finite temperature), and the study of giant resonances based on the atomic nucleus ground state (zero temperature). Research on the structure of hot nuclei is presented, providing experimentalist with a guide for uses of gamma ray detectors.

This thesis addresses in a very new and elegant way several measurements and the extraction of so-called double parton scattering. The new and elegant way lies in the combination of measurements and a very smart extraction of double parton scattering results, which is easy to apply and overcomes many of the technical difficulties of older methods. Many new phenomena in particle physics can be observed when particles are collided at the highest energies; one of the highlights in recent years was the discovery of the Higgs boson at the Large Hadron Collider at CERN. Understanding the production mechanism of the Higgs boson at the LHC requires detailed knowledge of the physics of proton-proton collisions. When the density of partons in the protons becomes large, there is a non-negligible probability that more than one parton participates in the interaction and the so-called double parton scattering becomes important. In some cases very particular final state signatures can be observed, which can be regarded as an indication of such double partonic scattering and where the different interactions can be separated. Such multiple partonic interactions play an important role when precise predictions from known processes are required.
Aimed primarily at operating organizations of nuclear power plants (NPPs) and regulatory bodies, this Safety Guide provides specific recommendations to ensure that operations in NPPs are conducted in a safe, effective, thorough and professional manner. It identifies the main responsibilities and operating practices in relation to such safe operation. The structure of the operations department, which is the part of the operating organization responsible for the conduct of operations of an NPP is addressed. Also addressed are the setting of high standards of performance and making safety related decisions in an effective manner, conducting control room activities in a thorough and professional manner and maintaining a nuclear power plant within the established operational limits and conditions.
Despite advances in the long-range electrostatic double-layer force, which depends strongly on ionic strength in water by using theoretical models such as DLVO (Derjaguin, Landau, Verwey, and Overbeek), the structure of confined water in air still remains widely unknown and has led to a variety of unexplained phenomena. This book bridges that gap by introducing a newly developed scanning probe miscroscopy (SPM) approach, which enables one to probe confined water at the molecular and atomic scale. Written by the developer of SPM, this book covers this new approach, as well as original approaches to addressing general interfacial water issues. It also introduces the cantilever-based optical interfacial force microscope (COIFM), which was invented by the author along with the methodology. The improved understanding will contribute to liquid-based nano- and bio-technologies such as lab-on-a-chip technologies, nanofluidic devices, dip-pen nanolithography, nano-oxidation, water-based granular interactions, liquid-based nanolubricants, hydration layers in biopolymers, manipulation of biomolecules, protein folding, stability of colloid suspensions, enzyme activity, swelling in clays, development of bioactive surfaces, water columns and ion channeling in membranes and scanning probe microscopy (SPM). It will also contribute to the improved performance of moving components in silicon-based micro-electro-mechanical system (MEMS) devices, where water plays a key role in interfacial interactions.
This book details groundbreaking experiments for the sensing and imaging of terahertz-frequency electromagnetic radiation (THz) using Rydberg atoms. The major advances described include the development and implementation of a new technique for THz imaging using atomic fluorescence; the demonstration of a THz-driven phase transition in room-temperature atomic vapour; and a novel method for probing the excited-state dynamics of atoms using quantum beats. The work has formed the basis for several articles published in journals including Nature Photonics and the Physical Review, and has sparked industry interest, becoming the subject of ongoing collaborative research and development. This exceptionally well-written book provides a definitive account of terahertz sensing with Rydberg atoms.
This volume contains papers presented at an international conference on nuclear astrophysics, which brought together astronomers, astrophysicists and nuclear physicists for a discussion of nucleosynthesis, its role in the evolution of the universe and its possibilities as a diagnostic tool for stellar interiors. The contributions have been divided into the following sections: astronomical facts; nuclear physics; the early universe and galactic evolution; and stellar models and nucleosynthesis.
applications to the structure of atomic nuclei. The author systematically develops these models from the elementary level, through an introduction to tensor algebra, to the use of group theory in spectroscopy. The book's extensive and detailed appendix includes a large selection of useful formulae of tensor algebra and spectroscopy. The serious graduate student, as well as the professional physicist, will find this complete treatment of the shell model to be an invaluable addition to the literature.
