Download or read book Project Y written by Los Alamos Scientific Laboratory and published by . This book was released on 2017-04-26 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: These two volumes constitute a record of the technical, administrative, and policy-making activities of the Los Alamos Project (Project Y) from its inception under the Manhattan District through the development of the atomic bomb (Vol. I), and during the period following the end of World War II until the Manhattan District relinquished control to the Atomic Energy Commission as of January 1947 (Vol. II). Project Y, the Los Alamos Project, has been one of a group of organizations known collectively as the Development of Substitute Materials project, (DSM), devoted to the wartime development of the atomic bomb. This branch of the DSM organization was created early in the year 1943. During the period of its existence it has been the center of activities connected with bomb development and production, as distinguished from the development and production of nuclear explosive materials. The history of all DSM activities possesses a peculiar interest and importance, not only because of the remarkable achievements and potentialities of nuclear technology, but also because of the wartime character and motivation of its initial development. Because of its large social cost, a scrupulous accounting of the entire venture is required. Project Y has been, of itself, small compared to the other DSM projects. It has, however, occupied a crucial position. The wartime success of the entire undertaking has depended upon its success. The nature of the present chronicle of Los Alamos is thus determined by the requirement that there exist a careful accounting of its technical, administrative, and policy-making activities. This document is a record, not an interpretation of events. Within the limitations thus implied, however, it has not been forgotten that the events recorded have taken place within a wider context, the evolution of organized scientific research and of world technology. The problems of organization and policy that lie here, sharpened by the advent of control over nuclear energies, will call for the most searching interpretation and analysis. It is hoped that in this record of fact nothing has been omitted or slighted that may be of interest to those who seek light upon questions still to be answered.

Download or read book The Los Alamos Primer written by Robert Serber and published by . This book was released on 2020 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than seventy years ago, American forces exploded the first atomic bombs over the Japanese cities of Hiroshima and Nagasaki, causing great physical and human destruction. The young scientists at Los Alamos who developed the bombs, which were nicknamed Little Boy and Fat Man, were introduced to the basic principles and goals of the project in March 1943, at a crash course in new weapons technology. The lecturer was physicist Robert Serber, J. Robert Oppenheimer's protégé, and the scientists learned that their job was to design and build the world's first atomic bombs. Notes on Serber's lectures were gathered into a mimeographed document titled TheLos Alamos Primer, which was supplied to all incoming scientific staff. The Primer remained classified for decades after the war. Published for the first time in 1992, the Primer offers contemporary readers a better understanding of the origins of nuclear weapons. Serber's preface vividly conveys the mingled excitement, uncertainty, and intensity felt by the Manhattan Project scientists. This edition includes an updated introduction by Pulitzer Prize-winning historian Richard Rhodes. A seminal publication on a turning point in human history, The Los Alamos Primer reveals just how much was known and how terrifyingly much was unknown midway through the Manhattan Project. No other seminar anywhere has had greater historical consequences.

Available in PDF, EPUB and Kindle. Book excerpt: "Nuclear weapons, since their conception, have been the subject of secrecy. In the months after the dropping of the atomic bombs on Hiroshima and Nagasaki, the American scientific establishment, the American government, and the American public all wrestled with what was called the "problem of secrecy," wondering not only whether secrecy was appropriate and effective as a means of controlling this new technology but also whether it was compatible with the country's core values. Out of a messy context of propaganda, confusion, spy scares, and the grave counsel of competing groups of scientists, what historian Alex Wellerstein calls a "new regime of secrecy" was put into place. It was unlike any other previous or since. Nuclear secrets were given their own unique legal designation in American law ("restricted data"), one that operates differently than all other forms of national security classification and exists to this day. Drawing on massive amounts of declassified files, including records released by the government for the first time at the author's request, Restricted Data is a narrative account of nuclear secrecy and the tensions and uncertainty that built as the Cold War continued. In the US, both science and democracy are pitted against nuclear secrecy, and this makes its history uniquely compelling and timely"--

The text describes the energetics and timescales of fast-neutron chain reactions, why only certain isotopes of uranium and plutonium are suitable for use in fission weapons, how critical mass and bomb yield can be estimated, how the efficiency of nuclear weapons can be enhanced, how the fissile forms of uranium and plutonium were obtained, some of the design details of the 'Little Boy' and 'Fat Man' bombs, and some of the thermal, shock, and radiation effects of nuclear weapons. Calculation exercises are provided, and a Bibliography lists authoritative print and online sources of information for readers who wish to pursue more detailed study of this fascinating topic.

Download or read book The History and Science of the Manhattan Project written by Bruce Cameron Reed and published by Springer. This book was released on 2019-02-19 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of atomic bombs under the auspices of the U.S. Army’s Manhattan Project during World War II is considered to be the outstanding news story of the twentieth century. In this book, a physicist and expert on the history of the Project presents a comprehensive overview of this momentous achievement. The first three chapters cover the history of nuclear physics from the discovery of radioactivity to the discovery of fission, and would be ideal for instructors of a sophomore-level “Modern Physics” course. Student-level exercises at the ends of the chapters are accompanied by answers. Chapter 7 covers the physics of first-generation fission weapons at a similar level, again accompanied by exercises and answers. For the interested layman and for non-science students and instructors, the book includes extensive qualitative material on the history, organization, implementation, and results of the Manhattan Project and the Hiroshima and Nagasaki bombing missions. The reader also learns about the legacy of the Project as reflected in the current world stockpiles of nuclear weapons. This second edition contains important revisions and additions, including a new chapter on the German atomic bomb program and new sections on British and Canadian contributions to the Manhattan project and on feed materials. Several other sections have been expanded; reader feedback has been helpful in introducing minor corrections and improved explanations; and, last but not least, the second edition includes a detailed index.
