Available in PDF, EPUB and Kindle. Book excerpt: CHAPTER FOUR The Fission Bomb As a Trigger The use of a fission bomb as the trigger for a thermonuclear explosion raises the following serious problem: To ignite a thermo- nuclear explosive by a fission bomb, the thermonuclear material must be exposed in some way to the large energy flux of the fission explosion. [...] The diameter d of such a fuse must be of the same order of magnitude as the diameter of the fission bomb, that is, of the order ~10 cm. [...] P is the point where the incoming wave intersects with the wall; M is the Mach number of the hypersonic flow associated with the diverging wave at P; 6 is the angle between the wall slope and the incoming ray; r, and r2 are the rays of the shock wave. [...] The pressure in the second focus of the Prandtl-Meyer ellipsoid where the thermonuclear fuse is placed is the same as the pressure at the surface of the exploding fission bomb, provided the wave focusing is completely isentropic. [...] From the theory of plane shock waves it follows that for a given temperature T behind the shock front the propagation velocity of the shock wave is proportional to A~,n, where A is the atomic weight of the material through which the shock propagates.

Book excerpt: This book (an improved English version of the one published in Portuguese in 2009) deals with topics essential to understanding the physics of nuclear explosives. Prepared based on strictly academic scientific activity, it is intended for those who wish to know more deeply the theory and physical processes involved in nuclear explosions. The main topics covered are: neutronic and criticality (neutron transport); hydrodynamics and thermodynamics at high temperatures and densities; dense and heavy plasmas; opacity and transport of thermal radiation; hydrodynamic theory of chemical detonations; shock waves, dynamic compression of solids, implosions; statistics of fission chain reactions; and inertial confinement fusion (thermonuclear detonations). Three types of explosives are analyzed: Pure fission explosives, the so-called "boosted bombs" (with the introduction of deuterium-tritium into the fissile mass) and thermonuclear explosives. Results of complex numerical and computational simulations (many of which presumably have never been published in the open scientific literature) are presented and discussed.""The Physics of Nuclear Explosives" provides a rather comprehensive account of the physical principles involved in nuclear detonations, including both fission and fusion weapons. The author has broken new ground in presenting the results of his numerical simulations of nuclear detonations and characterizations of particular weapons, such as the W-87 warhead."

Download or read book Restricted Data written by Alex Wellerstein and published by University of Chicago Press. This book was released on 2024-04-23 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first full history of US nuclear secrecy, from its origins in the late 1930s to our post–Cold War present. The American atomic bomb was born in secrecy. From the moment scientists first conceived of its possibility to the bombings of Hiroshima and Nagasaki and beyond, there were efforts to control the spread of nuclear information and the newly discovered scientific facts that made such powerful weapons possible. The totalizing scientific secrecy that the atomic bomb appeared to demand was new, unusual, and very nearly unprecedented. It was foreign to American science and American democracy—and potentially incompatible with both. From the beginning, this secrecy was controversial, and it was always contested. The atomic bomb was not merely the application of science to war, but the result of decades of investment in scientific education, infrastructure, and global collaboration. If secrecy became the norm, how would science survive? Drawing on troves of declassified files, including records released by the government for the first time through the author’s efforts, Restricted Data traces the complex evolution of the US nuclear secrecy regime from the first whisper of the atomic bomb through the mounting tensions of the Cold War and into the early twenty-first century. A compelling history of powerful ideas at war, it tells a story that feels distinctly American: rich, sprawling, and built on the conflict between high-minded idealism and ugly, fearful power.

Download or read book Handbook on Plasma Instabilities written by Ferdinand F. Cap and published by Academic Press. This book was released on 2013-09-11 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook on Plasma Instabilities, Volume 3, is primarily intended to serve as a sourcebook for obtaining quick information and literature references pertaining to a specific topic. Such a handbook has to be formulated in a way that enables understanding of any one section without requiring full understanding of any other section. Volume 1 (Chapters 1-13) presents the fundamental concepts of plasma physics with applications, and has more the nature of a textbook treating basic plasma physics, containment, waves, and macroscopic instabilities. Volume 2 (Chapters 14-17) covers various aspects of microinstabilities, beam plasma systems, stabilization methods, and parametric effects. The present volume (Chapters 18-22) starts with a discussion on feedback and dynamic stabilization using parametric and other effects. It then treats nonlinear effects and laser-plasma systems. One chapter is devoted to applications and use of instabilities. It concludes with a report on plasma waves and instabilities in cosmic space.

Available in PDF, EPUB and Kindle. Book excerpt: How the chemical engineering behemoth that brought us Teflon, Kevlar, Lycra, Freon, and more shaped the culture of postwar America. What do nylon stockings and atomic bombs have in common? DuPont. The chemical firm of DuPont de Nemours pioneered the development of both nylon and plutonium, among countless other innovations, playing an important role in the rise of mass consumption and the emergence of the notorious “military-industrial complex.” In this fascinating account of the lives and careers of Du Pont’s chemical engineers, Pap A. Ndiaye deftly illustrates the contribution of industry to the genesis of a dominant post–World War II “American model” connecting prosperity with security. The consumer and military dimensions of twentieth-century American history are often studied separately. Ndiaye reunites them by examining Du Pont’s development of nylon, which symbolized a new way of life, and plutonium, which was synonymous with annihilation. Reflecting on the experiences and contributions of the company’s engineers and physicists, Ndiaye traces Du Pont’s transformation into one of the corporate models of American success.
Download or read book Dimensional Analysis Beyond the Pi Theorem written by Bahman Zohuri and published by Springer. This book was released on 2016-11-02 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dimensional Analysis and Physical Similarity are well understood subjects, and the general concepts of dynamical similarity are explained in this book. Our exposition is essentially different from those available in the literature, although it follows the general ideas known as Pi Theorem. There are many excellent books that one can refer to; however, dimensional analysis goes beyond Pi theorem, which is also known as Buckingham’s Pi Theorem. Many techniques via self-similar solutions can bound solutions to problems that seem intractable. A time-developing phenomenon is called self-similar if the spatial distributions of its properties at different points in time can be obtained from one another by a similarity transformation, and identifying one of the independent variables as time. However, this is where Dimensional Analysis goes beyond Pi Theorem into self-similarity, which has represented progress for researchers. In recent years there has been a surge of interest in self-similar solutions of the First and Second kind. Such solutions are not newly discovered; they have been identified and named by Zel’dovich, a famous Russian Mathematician in 1956. They have been used in the context of a variety of problems, such as shock waves in gas dynamics, and filtration through elasto-plastic materials. Self-Similarity has simplified computations and the representation of the properties of phenomena under investigation. It handles experimental data, reduces what would be a random cloud of empirical points to lie on a single curve or surface, and constructs procedures that are self-similar. Variables can be specifically chosen for the calculations.
Download or read book Building The H Bomb A Personal History written by Kenneth W Ford and published by World Scientific. This book was released on 2015-03-25 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this engaging scientific memoir, Kenneth Ford recounts the time when, in his mid-twenties, he was a member of the team that designed and built the first hydrogen bomb. He worked with — and relaxed with — scientific giants of that time such as Edward Teller, Enrico Fermi, Stan Ulam, John von Neumann, and John Wheeler, and here offers illuminating insights into the personalities, the strengths, and the quirks of these men. Well known for his ability to explain physics to nonspecialists, Ford also brings to life the physics of fission and fusion and provides a brief history of nuclear science from the discovery of radioactivity in 1896 to the ten-megaton explosion of “Mike” that obliterated a Pacific Island in 1952.Ford worked at both Los Alamos and Princeton's Project Matterhorn, and brings out Matterhorn's major, but previously unheralded contribution to the development of the H bomb. Outside the lab, he drove a battered Chevrolet around New Mexico, a bantam motorcycle across the country, and a British roadster around New Jersey. Part of the charm of Ford's book is the way in which he leavens his well-researched descriptions of the scientific work with brief tales of his life away from weapons.
