Book Synopsis Fundamental Physics with Cold Neutron Beams by : Kyle Brandon Grammer
Download or read book Fundamental Physics with Cold Neutron Beams written by Kyle Brandon Grammer and published by . This book was released on 2016 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The neutron exhibits rich physics both as a tool for studying materials, particle and nuclear physics, as well as the object of experimental study. The neutron lifetime is an important input to Big Bang Nucleosynthesis models and is currently known only to approximately 0.3% with the most precise measurements from two different experimental techniques in disagreement by more than 3 [sigma]. Parity violation has been the subject of study since its discovery in 1957. Parity violation experiments provide access to studying the hadronic weak interaction, which is otherwise suppressed by several orders of magnitude below that of the strong interaction. It is the hadronic weak interaction that the NPDGamma experiment accesses via studying the asymmetry in gamma ray emission from the capture of polarized neutrons on liquid parahydrogen. Finally, as part of the NPDGamma experiment, the opportunity arose to use the well known and characterized apparatus for conducting a measurement of the liquid parahydrogen scattering cross section which has important implications in the design of neutron sources and moderators at cold neutron research facilities.

Download or read book Workshop Summary written by and published by . This book was released on 2001 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-energy neutrons from reactor and spallation neutron sources have been employed in a wide variety of investigations that shed light on important issues in nuclear, particle, and astrophysics; in the elucidation of quantum mechanics; in the determination of fundamental constants; and in the study of fundamental symmetry violation (Appendix A, Glossary). In many cases, these experiments provide important information that is not otherwise available from accelerator-based nuclear physics facilities or high energy accelerators. An energetic research community in the United States is engaged in ''fundamental'' neutron physics. With exciting recent results, the possibility of new and upgraded sources, and a number of new experimental ideas, there is an important opportunity for outstanding science in the next decade. ''Fundamental'' neutron physics experiments are usually intensity limited. Researchers require the highest flux neutron sources available, which are either high-flux reactors (continuous sources) or spallation neutron sources (pulsed sources). The primary mission of these major facilities is neutron scattering for materials science research. Notwithstanding this condensed matter focus, essentially all neutron scattering facilities have accepted the value of an on-site fundamental physics program and have typically allocated 5 to 10% of their capabilities (i.e., beam lines) toward nuclear and particle physics research activities.

Download or read book Astrophysics, Symmetries, And Applied Physics At Spallation Neutron Sources, Proceedings Of The Workshop On Asap 2002 written by Christopher R Gould and published by World Scientific. This book was released on 2002-12-26 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The spallation neutron source (SNS) being built at the Oak Ridge National Laboratory (ORNL) will be by far the highest flux pulsed source of epithermal neutrons in the world when it comes on line in 2006. Although the main thrust of the science program at the SNS will be materials science, the facility could provide outstanding opportunities for research in nuclear astrophysics, fundamental symmetries, and applied nuclear physics. To review the current status of these fields and to begin to assemble the scientific case and the community of researchers for future experiments at the SNS, a workshop on “Astrophysics, Symmetries, and Applied Physics” was held in March 2002 at the ORNL. Over 60 scientists, representing 11 US and 4 foreign universities as well as many national laboratories around the world, participated in the workshop. The proceedings describe the current state of research in those fields and the future opportunities at the SNS.

Book Synopsis Strangeness and Spin in Fundamental Physics by : M. Anselmino
Download or read book Strangeness and Spin in Fundamental Physics written by M. Anselmino and published by IOS Press. This book was released on 2008-07-14 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strangeness and Spin in Fundamental Physics is dedicated to the discussion of the role played by two subtle and somehow puzzling quantum numbers, the strangeness and the spin, in fundamental physics. They both relate to basic properties of the fundamental quantum field theories describing strong and electro-weak interactions and to their phenomenological applications. In some instances, like the partonic spin structure of the proton, they are deeply correlated. The many puzzling results recently obtained by measuring several spin asymmetries have stimulated gigantic progresses in the study of the spin structure of protons and neutrons. Intense theoretical activity has discovered new features of non-perturbative QCD, like strong correlations between the spin and the intrinsic motions of quarks inside the nucleons. The purpose of this publication is that of providing a complete, updated and critical account of the most recent and relevant discoveries in the above fields, both from the experimental and theoretical sides.

Book Synopsis Ultracold Neutrons by : Albert Steyerl
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 Synopsis Fundamental Research with Polarized Slow Neutrons by : Pyotr Aleksandrovich Krupchitsky
Download or read book Fundamental Research with Polarized Slow Neutrons written by Pyotr Aleksandrovich Krupchitsky and published by Springer. This book was released on 2014-04-13 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last twenty years polarized beams of slow neutrons have been used effectively in fundamental research in nuclear physics. Parity violation in nuclear fission and neutron optics was discoverd as well as the nuclear precession of neutrons and the coherent interference of spin channels in neutron capture by nuclei. Furthermore, these methods helped to understand better the neutron`s electric dipole moment and its beta decay. This book gives a thorough introduction to these experimental methods including the most recent techniques of generating and analyzing polarized neutral beams. It clearly shows the close relationship between elementary particle physics and nuclear physics, in particular in the section dealing with the effects caused by weak interactions. Special attention is paid to experiments which investigate the violation of quantum mechanical conservation laws. The book not only addresses specialists but also those interested in the foundations of elementary particle and nuclear physics. It is well suited as additional reading for students.
