Download or read book Next Generation Experiments To Measure The Neutron Lifetime Proceedings Of The Workshop written by Susan J Seestrom and published by World Scientific. This book was released on 2014-03-28 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a great interest in improving the limits on neutron lifetime to the level of a precision of 0.1 s. The neutron lifetime is both an important fundamental quantity as well as a parameter influencing important processes such as nucleosynthesis (Helium production in the early universe) and the rate of energy production in the Sun.Aiming to create a roadmap of R&D for a next generation neutron lifetime experiment that can be endorsed by the North American neutron community, the focus of the workshop was on experiments using traps that utilize ultracold neutrons and confinement by a combination of magnetic and/or gravitational interaction in order to avoid systematic uncertainties introduced by neutron interactions with material walls. The papers in this volume summarize the limitations of present experiments, the discussion of new experiments in planning stage, and the discussion of systematic effects that must be addressed to achieve a lifetime measurement at an accuracy of 0.1 second.Cover image courtesy of Elena Fernández, Los Alamos National Laboratory.

Available in PDF, EPUB and Kindle. Book excerpt: Low energy neutron beams are used to address many questions in nuclear physics, particle physics and astrophysics. The scientific issues include elucidating the nature of time reversal noninvariance; understanding the origin of the baryon asymmetry in the Universe; describing the weak interaction between quarks and between nucleons; understanding the origin of the elements in stellar and big bang nucleosynthesis.This book summarizes how spallation neutron sources work and discuss the advantages of pulsed beams in reducing systematic errors in precision measurements. It also describes recent breakthroughs in ultracold neutron production, together with the physics that will be addressed by the new generation of intense neutron sources.

Download or read book Ultracold Neutrons written by Albert Steyerl and published by World Scientific. This book was released on 2020-05-26 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultracold Neutrons is a guide to a fascinating topic. It describes how a simple new idea in experimental neutron physics has changed the landscape of what is often called 'fundamental physics.' Ultracold neutrons (UCNs) are neutrons moving at the low speed of a bicycle rider. They were produced for the first time 50 years ago (in 1968) and are distinguished from ordinary neutrons with much higher energies by their ability to be confined in 'neutron bottles' for durations up to several hundred seconds. This is possible since they are reflected back and forth from the container walls many thousands of times with very little loss. As a result of these long observation times, their properties and interactions with the environment can be studied with superb precision.Directed towards a general readership, this book is an excellent introduction to a field of research that is not highly specialized but touches on many aspects of our physical world, classical as well as quantum mechanical.

Book excerpt: Radioactivity: History, Science, Vital Uses and Ominous Peril, Third Edition provides an introduction to radioactivity, the building blocks of matter, the fundamental forces in nature, and the role of quarks and force carrier particles. This new edition adds material on the dichotomy between the peaceful applications of radioactivity and the threat to the continued existence of human life from the potential use of more powerful and sophisticated nuclear weapons. The book includes a current review of studies on the probability of nuclear war and treaties, nonproliferation and disarmament, along with historical insights into the achievements of over 100 pioneers and Nobel Laureates. Through multiple worked examples, the book answers many questions for the student, teacher and practitioner as to the origins, properties and practical applications of radioactivity in fields such as medicine, biological and environmental research, industry, safe nuclear power free of greenhouse gases and nuclear fusion. Ratings and Reviews of Previous Editions: CHOICE Magazine, July 2008: "This work provides an overview of the many interesting aspects of the science of radioactive decays, including in-depth chapters that offer reminiscences on the history and important personalities of the field...This book can be useful as supplemental reading or as a reference when developing course material for nuclear physics, nuclear engineering, or health physics lectures. Special attention has been given to a chapter on the role radioactivity plays in everyday life applications...Generally the book is well produced and will be a valuable resource...Many lectures can be lightened up by including material from this work. Summing up: RECOMMENDED. Upper division undergraduates through professionals; technical program students." U. Greife, Colorado School of Mines, USA "I found the biographical accounts of the various stalwarts of Physics inspirational. Most of them, if not all, had to overcome economic hardships or p[ersonal tragedies or had to do their groundbreaking work in the face of tyranny and war. The biographies also highlighted the high standards of moral convictions that the scientists had as they realized the grave implications of some of their work and the potential threats to humanity. This ought to inspire and motivate young men and women aspiring to be physicists. Even people who have been in the field for a while should find your book re-energizing. It certainly had that effect on me." -- Dr. Ramkumar Venkataraman, Canberra Industries, Inc., Meriden, CT, USA Winner of an Honorable Mention in the 2017 PROSE Awards in the category of Chemistry and Physics (https://proseawards.com/winners/2017-award-winners/ ) - Includes new content that explains the vital benefits that nuclear technology provides and the need to be aware and involved in worldwide efforts toward the reduction of nuclear weapon stockpiles and the elimination of the threat of nuclear weapons - Provides context and insights on key research over the past three centuries, placing radioactivity in real-world contexts - Supports learning via multiple solved problems that answer practical questions concerning nuclear decay, nuclear radiation and the interaction of nuclear radiation with matter

This book was released on 2008-11-27 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mission of the NIST Physics Laboratory is to support U.S. industry, government, and the scientific community by providing measurement services and research for electronic, optical, and radiation technology. In this respect, the laboratory provides the foundation for the metrology of optical and ionizing radiations, time and frequency, and fundamental quantum processes, historically major areas of standards and technology. The Panel on Physics visited the six divisions of the laboratory and reviewed a selected sample of their programs and projects. This book finds that the overall quality and productivity of the Physics Laboratory are comparable to or better than those of other peer institutions, an accomplishment that is being achieved with an infrastructure that is smaller in both size and funding than the size and funding of most national and agency laboratories in the United States.
