TO THE SECOND EDITION In the nine years since this book was first written, rapid progress has been made scientifically in nuclear fusion, space physics, and nonlinear plasma theory. At the same time, the energy shortage on the one hand and the exploration of Jupiter and Saturn on the other have increased the national awareness of the important applications of plasma physics to energy production and to the understanding of our space environment. In magnetic confinement fusion, this period has seen the attainment 13 of a Lawson number nTE of 2 x 10 cm -3 sec in the Alcator tokamaks at MIT; neutral-beam heating of the PL T tokamak at Princeton to KTi = 6. 5 keV; increase of average ß to 3%-5% in tokamaks at Oak Ridge and General Atomic; and the stabilization of mirror-confined plasmas at Livermore, together with injection of ion current to near field-reversal conditions in the 2XIIß device. Invention of the tandem mirror has given magnetic confinement a new and exciting dimension. New ideas have emerged, such as the compact torus, surface-field devices, and the EßT mirror-torus hybrid, and some old ideas, such as the stellarator and the reversed-field pinch, have been revived. Radiofrequency heat ing has become a new star with its promise of dc current drive. Perhaps most importantly, great progress has been made in the understanding of the MHD behavior of toroidal plasmas: tearing modes, magnetic Vll Vlll islands, and disruptions.

For more than thirty years, the prospect of unlimited fusion energy has attracted scientists and the public. Joan Lisa Bromberg's book documents the history of the American magnetic fusion reactor program. It is also a lively account that will inform interested citizens of limited technical background who are concerned with the nation's energy strategy. The book carries the story from the program's inception under the auspices of the Atomic Energy Commission in 1951 to its operations under the then-new Department of Energy in 1978. Fusion concentrates on the four federally funded laboratories where most of the money has been spent (about $2 billion so far): Oak Ridge, Los Alamos, Lawrence Livermore, and Princeton. It recounts the crucial experiments along the way - the ones that succeeded, the ones that failed, the ones that showed promise. And it explains and diagrams the various magnetic configurations and devices that were developed and tested: the stellarator, the pinch, the mirror, the tokamak. With the government and the public constantly looking over the scientists' shoulders, it is no surprise that research directions were heavily influenced by extrascientific pressures: the major decisions in fusion research have always emerged from a medley of technical, institutional, and political considerations. The intermingling of science and politics is demonstrated in specific detail. The magnetic fusion reactor project is, of course, ongoing. Latest target date for producing commercial power: 2050. Estimated total cost: $15 billion. Dr. Bromberg has written extensively on topics in the history of modern science.

This textbook accommodates the two divergent developmental paths which have become solidly established in the field of fusion energy: the process of sequential tokamak development toward a prototype and the need for a more fundamental and integrative research approach before costly design choices are made.Emphasis is placed on the development of physically coherent and mathematically clear characterizations of the scientific and technological foundations of fusion energy which are specifically suitable for a first course on the subject. Of interest, therefore, are selected aspects of nuclear physics, electromagnetics, plasma physics, reaction dynamics, materials science, and engineering systems, all brought together to form an integrated perspective on nuclear fusion and its practical utilization.The book identifies several distinct themes. The first is concerned with preliminary and introductory topics which relate to the basic and relevant physical processes associated with nuclear fusion. Then, the authors undertake an analysis of magnetically confined, inertially confined, and low-temperature fusion energy concepts. Subsequently, they introduce the important blanket domains surrounding the fusion core and discuss synergetic fusion-fission systems. Finally, they consider selected conceptual and technological subjects germane to the continuing development of fusion energy systems.

In the realm of human innovation, few pursuits have captured our imagination quite like the quest for fusion power. It is a journey marked by scientific curiosity, technological ingenuity, and the aspiration for a sustainable energy future. From the intricacies of plasma physics to the engineering marvels of containment vessels, the pursuit of fusion has spurred collaboration across disciplines and nations, offering tantalizing promises of clean, abundant energy. This book seeks to unravel the complexities surrounding fusion power, providing a comprehensive overview of its science, technology, and potential impact on our world. It delves into the fundamental principles that govern fusion reactions, explores the various approaches to achieving controlled fusion, and examines the challenges that lie ahead on the path to practical fusion energy. While the concept of fusion has been studied for decades, recent advancements in fusion research have brought us closer than ever to realizing its potential. Breakthroughs in materials science, computational modeling, and fusion reactor design have reignited optimism within the scientific community and sparked renewed interest from policymakers and industry leaders. However, the road to fusion energy is not without obstacles. Technical hurdles, funding constraints, and public perception issues pose formidable barriers to overcome. Yet, with perseverance and innovation, the dream of harnessing the power of the stars in a controlled manner is within reach. As we stand on the brink of a new era in energy production, it is imperative that we confront the challenges of our time with resolve and determination. Fusion power represents a beacon of hope in our quest for a sustainable future, offering the promise of clean, reliable energy for generations to come. This book serves as a testament to the remarkable progress made in the field of fusion research and a call to action for continued investment and collaboration. By exploring the science, technology, and potential of fusion power, we hope to inspire readers to join us on this transformative journey towards a brighter tomorrow. Welcome to the fusion revolution.

For over 60 years, scientists and engineers have been trying to crack a seemingly intractable problem: how to build practical devices that exploit nuclear fusion. Access to electricity has facilitated a standard of living that was previously unimaginable, but as the world’s population grows and developing nations increasingly reap the benefits of electrification, we face a serious global problem: burning fossil fuels currently produces about eighty percent of the world's energy, but it produces a greenhouse effect that traps outgoing infrared radiation and warms the planet, risking dire environmental consequences unless we reduce our fossil fuel consumption to near zero in the coming decades. Nuclear fusion, the energy-producing process in the sun and stars, could provide the answer: if it can be successfully harnessed here on Earth, it will produce electricity with near-zero CO2 byproduct by using the nuclei in water as its main fuel. The principles behind fusion are understood, but the technology is far from being fully realized, and governments, universities, and venture capitalists are pumping vast amounts of money into many ideas, some highly speculative, that could lead to functioning fusion reactors. This book puts all of these attempts together in one place, providing clear explanations for readers who are interested in new energy technologies, including those with no formal training in science or engineering. For each of the many approaches to fusion, the reader will learn who pioneered the approach, how the concept works in plain English, how experimental tests were engineered, the future prospects, and comparison with other approaches. From long-established fusion technologies to emerging and exotic methods, the reader will learn all about the idea that could eventually constitute the single greatest engineering advance in human history.
