Ion and Atomic Beams for Controlled Fusion and Technology


Book Description

A beam of ions in the fonn of "canal rays" was first observed in 1886 by E. Goldstein. The first ion source was invented by J. J. Thomson in 1910. This ion source became the basis for the first widespread application of ion sources in mass spectrographs and mass spectrometers. The second important application of ion sources is ion accelerators, which since the beginning of the 1930s have been employed in research on nuclear reactions and are now used in industry and medicine. A third application of ion sources is in systems for isotope separation and re search on the interaction of atomic particles with solids (1940s). The result of this research and development is the use of ion sources in semiconductor doping, decontamination of surfaces, and micromachining of surfaces (1960s and' 1970s), which is a fourth area of applications for ion sources. The heating of plasmas in magnetic confinement devices to thennonuclear temperatures (100-1000 MK) with the aid of megawatt beams of hydrogen and deuterium ions and atoms has become a fifth promising area of application for ion sources which can produce ion beams with steady-state currents of up to 100 A. Finally, experimental and industrial research are under way on the alloying of metals and the fabrication of coatings which greatly improve the physical and chemical properties of metals. These coatings can increase the hardness, high temperature corrosion resistance, and wear resistance of metals, and can enhance or reduce friction, etc.




Atomic Physics with Heavy Ions


Book Description

This book is devoted to one of the most active domains of atomic physic- atomic physics of heavy positive ions. During the last 30 years, this terrain has attracted enormous attention from both experimentalists and theoreti cians. On the one hand, this interest is stimulated by rapid progress in the development of laboratory ion sources, storage rings, ion traps and methods for ion cooling. In many laboratories, a considerable number of complex and accurate experiments have been initiated, challenging new frontiers. Highly charged ions are used for investigations related to fundamental research and to more applied fields such as controlled nuclear fusion driven by heavy ions and its diagnostics, ion-surface interaction, physics of hollow atoms, x-ray lasers, x-ray spectroscopy, spectrometry of ions in storage rings and ion traps, biology, and medical therapy. On the other hand, the new technologies have stimulated elaborate theo retical investigations, especially in developing QED theory, relativistic many body techniques, plasma-kinetic modeling based on the Coulomb interactions of highly charged ions with photons and various atomic particles - electrons, atoms, molecules and ions. The idea of assembling this book matured while the editors were writ ing another book, X-Ray Radiation of Highly Charged Ions by H. F. Beyer, H. -J. Kluge and V. P. Shevelko (Springer, Berlin, Heidelberg 1997) covering a broad range of x-ray and other radiative phenomena central to atomic physics with heavy ions.

Fusion


Book Description

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.




Ion Beam Techniques and Applications


Book Description

A wide variety of ion beam techniques are being used in several versatile applications ranging from environmental science, nuclear physics, microdevice fabrication to materials science. In addition, new applications of ion beam techniques across a broad range of disciplines and fields are also being discovered frequently. In this book, the latest research and development on progress in ion beam techniques has been compiled and an overview of ion beam irradiation-induced applications in nanomaterial-focused ion beam applications, ion beam analysis techniques, as well as ion implantation application in cells is provided. Moreover, simulations of ion beam-induced damage to structural materials of nuclear fusion reactors are also presented in this book.




Induction Accelerators


Book Description

A broad class of accelerators rests on the induction principle whereby the accelerating electrical fields are generated by time-varying magnetic fluxes. Particularly suitable for the transport of bright and high-intensity beams of electrons, protons or heavy ions in any geometry (linear or circular) the research and development of induction accelerators is a thriving subfield of accelerator physics. This text is the first comprehensive account of both the fundamentals and the state of the art about the modern conceptual design and implementation of such devices. Accordingly, the first part of the book is devoted to the essential features of and key technologies used for induction accelerators at a level suitable for postgraduate students and newcomers to the field. Subsequent chapters deal with more specialized and advanced topics.
