Available in PDF, EPUB and Kindle. Book excerpt: Most of this book was written before October 1973. Thus the statements concerning the energy crisis are now dated, but remain valid nevertheless. However, the term "energy crisis" is no longer the unusual new concept it was when the material was written; it is, rather, a commonplace expression for a condition with which we are all only too familiar. The purpose of this book is to point out that the science and technology of laser-induced nuclear fusion are an extraordinary subject, which in some way not yet completely clear can solve the problem of gaining a pollution-free and really inexhaustible supply of inexpensive energy from the heavy hydrogen (deuterium) atoms found in all terrestrial waters. The concept is very obvious and very simple: To heat solid deuterium or mixtures of deuterium and tritium (superheavy hydrogen) by laser pulses so rapidly that despite the resulting expansion and cooling there still take place so many nuclear fusion reactions tnat the energy produced is greater than the laser energy that had to be applied. Compression of the plasma by the laser radiation itself is a more sophisticated refinement of the process, but one which at the present stage of laser cechnology is needed for the rapid realization of a laser-fusion reactor for power generation. This concept of compression can also be applied to the development of completely safe reactors with controlled microexplosions of laser-compressed fissionable materials such as uranium and even boron, which fission completely safely into nonradioactive helium atoms.

This book was released on 2013-07-17 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the fall of 2010, the Office of the U.S. Department of Energy's (DOE's) Secretary for Science asked for a National Research Council (NRC) committee to investigate the prospects for generating power using inertial confinement fusion (ICF) concepts, acknowledging that a key test of viability for this concept-ignition -could be demonstrated at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) in the relatively near term. The committee was asked to provide an unclassified report. However, DOE indicated that to fully assess this topic, the committee's deliberations would have to be informed by the results of some classified experiments and information, particularly in the area of ICF targets and nonproliferation. Thus, the Panel on the Assessment of Inertial Confinement Fusion Targets ("the panel") was assembled, composed of experts able to access the needed information. The panel was charged with advising the Committee on the Prospects for Inertial Confinement Fusion Energy Systems on these issues, both by internal discussion and by this unclassified report. A Panel on Fusion Target Physics ("the panel") will serve as a technical resource to the Committee on Inertial Confinement Energy Systems ("the Committee") and will prepare a report that describes the R&D challenges to providing suitable targets, on the basis of parameters established and provided to the Panel by the Committee. The Panel on Fusion Target Physics will prepare a report that will assess the current performance of fusion targets associated with various ICF concepts in order to understand: 1. The spectrum output; 2. The illumination geometry; 3. The high-gain geometry; and 4. The robustness of the target design. The panel addressed the potential impacts of the use and development of current concepts for Inertial Fusion Energy on the proliferation of nuclear weapons information and technology, as appropriate. The Panel examined technology options, but does not provide recommendations specific to any currently operating or proposed ICF facility.

Book excerpt: Thermal neutrons are of considerable interest to the Department of Defense and for commercial applications. Unlike high energy photons, neutrons easily penetrate high density targets, but get effectively absorbed by low density materials like paraffin, nylon or explosives. This makes them attractive complements to X-rays for radiographic applications, e.g. for the detection or inspection of explosives inside steel casings. The key challenge is to develop a compact generator for thermal neutrons with large enough flux. The limited availability of radio-isotopes, combined with the relatively short half-life, safety constraints and regulatory requirements make them unattractive for wide-spread use. An alternative design exploits the Deuterium-Tritium (D-T) fusion, which generates Alpha particles and fast neutrons. In these sources, Deuterium ions are accelerated to about 130 keV and hit a Tritium target. The acceleration of Deuterium ions is usually accomplished in a diode configuration. Recently, considerable success has been achieved in the acceleration of ions via laser-matter interaction. In this project we investigated whether laser-accelerated ions could undergo nuclear fusion in an adequately designed target and could be used for neutron sources. We therefore enhanced our proprietary plasma simulation code VORPAL with a model for fusion reactions and investigated the generation of neutrons in shaped D-T targets. We find that neutron fluxes large enough for radiographic applications can be generated by utilizing moderate (~ 10(exp 17)-10(exp 18) W/sq cm) laser intensities.

This book was released on 2012-12-06 with total page 667 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the third Workshop on "Laser Interaction and Related Plasma Phenomena" in 1973, one area within the scope of this con ference received increased attention: laser fusion. This possi bility was emphasized in February 1977 in a Seminar on US energy policies at The Hartford Graduate Center by John F. O'Leary, Head of the Federal Energy Administration, who said that "by the year 2100, ••• laser fusion will be coming along, giving us a new age of choice". Efforts in research and development were stepped up to investigate new concepts of laser ignition of controlled nuclear reactions. Here, one expects no radioactive waste from fuel. Th~ deuterium-tritium reaction - the only one which may be possible with magnetic field confinement in tokamaks - has a highly radio active tritium cycle, while, in principle, laser reactions are possible with pure deuterium, hydrogen-boron or others. The worldwide progress in laser compression was not only stim ulated by the energy crisis, but also by its advancements. In our first Workshop in 1969 F. Floux of the French Limeil Laboratories described his experiments, which led, only one month later, to the production of fusion neutrons in such large numbers as had not been achieved up to then (see appendix of Vol. I these Proceedings).

This book was released on 2005-06-28 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: How to achieve unlimited, safe, clean and low-cost energy by laser- or beam-driven inertial nuclear fusion has preoccupied all winners of the Edward Teller Medal since its inception in 1991. This book presents their findings, meeting discussions, and personal insights from Edward Teller himself. Expect discussion of important advances anticipated in the future such as multi-billion dollar fusion research projects (NIF), and new schemes such as the petawatt-picosecond laser-plasma interactions evoking new physics and coupling mechanisms.For the first time, laser technology of the new century is providing the very short and extremely intense energetic pulses needed for fusion energy from next generation power stations, which produce energy at several times lower cost than any other source. The long-sought dream to directly ignite frozen heavy hydrogen for controlled use is close to being realized. Years of research on plasmas and lasers carried out worldwide in highly sophisticated experiments is summarized. The coverage begins with the work of John Nuckolls and Nobel Laureate Nikolai Basov and leads to the new scheme of plasma block acceleration via the nonlinear ponderomotive force. Edward Teller Lectures is one of the first guides to these new developments./a

Download or read book Nuclear Physics of Stars written by Christian Iliadis and published by John Wiley & Sons. This book was released on 2015-04-13 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most elements are synthesized, or "cooked", by thermonuclear reactions in stars. The newly formed elements are released into the interstellar medium during a star's lifetime, and are subsequently incorporated into a new generation of stars, into the planets that form around the stars, and into the life forms that originate on the planets. Moreover, the energy we depend on for life originates from nuclear reactions that occur at the center of the Sun. Synthesis of the elements and nuclear energy production in stars are the topics of nuclear astrophysics, which is the subject of this book. It presents nuclear structure and reactions, thermonuclear reaction rates, experimental nuclear methods, and nucleosynthesis in detail. These topics are discussed in a coherent way, enabling the reader to grasp their interconnections intuitively. The book serves both as a textbook for advanced undergraduate and graduate students, with worked examples and end-of-chapter excercises, but also as a reference book for use by researchers working in the field of nuclear astrophysics.

Book excerpt: Laser induced fusion is the forerunner of a class of inertial confinement schemes in which hydrogen isotopes are heated to thermonuclear conditions in a very short period. The process is characterized by such short time scales that fuel confinement is achieved through its' own finite mass and expansion velocity, approaching 1 .mu.m/psec for ignition temperatures of order 10 keV (108 °K). With current laser powers limited to several terrawatts one readily estimates, on the basis of energy conservation, target mass, and expansion velocity, that target size and laser pulse duration are on the order of 100 .mu.m and 100 psec, respectively. Within these constraints, targets have been heated and confined to the point where thermonuclear conditions have been achieved. This paper describes a sampling of diagnostic techniques with requisite resolution (microns and picoseconds) to accurately describe the dynamics of a laser driven compression. As discussed in each case cited, these in turn provide insight to and quantitative measure of, the physical processes dominating the implosion. The success of the inertial confinement fusion program is strongly dependent on the continued development of such diagnostics and the understanding they provide.
