Available in PDF, EPUB and Kindle. Book excerpt: Pulsed spallation sources now operating in the world are at the KEK Laboratory in Japan (the KENS source), at Los Alamos National Laboratory (WNR) and at Argonne National Laboratory (IPNS), both the latter being in the US. The Intense Pulsed Neutron Source (IPNS) is currently the world's most intense source with a peak neutron flux of 4 x 1014 n cm−2s−1 at a repetition rate of 30 Hz, and globally producing approx. 1.5 x 1015 n/sec. Present pulsed sources are still relatively weak compared to their potential. In 1985 the Rutherford Spallation Neutron Source will come on line, and eventually be approx. 30 more intense than the present IPNS. Later, in 1986 the WNR/PSR option at Los Alamos will make that facility of comparable intensity, while a subcritical fission booster at IPNS will keep IPNS competitive. These new sources will expand the applications of pulsed neutrons but are still based on accelerators built for other scientific purposes, usually nuclear or high-energy physics. Accelerator physicists are now designing machines expressly for spallation neutron research, and the proton currents attainable appear in the milliamps. (IPNS now runs at 0.5 GeV and 14 .mu. A). Such design teams are at the KFA Laboratory Julich, Argonne National Laboratory and KEK. Characteristics, particularly the different time structure of the pulses, of these new sources will be discussed. S.
Book Synopsis Handbook of Spallation Research by : Detlef Filges
Download or read book Handbook of Spallation Research written by Detlef Filges and published by Wiley-VCH. This book was released on 2010-02-01 with total page 787 pages. Available in PDF, EPUB and Kindle. Book excerpt: This detailed and comprehensive reference to spallation -- from the foundations to the latest applications is the only work of its kind and is written by two internationally renowned researchers. Clearly divided into three parts, it begins with the basic principles, while the second part describes the proton-nucleus and proton-matter experiments so-called thin and thick target experiments in terms of secondary particle production as hadrons, pions, muons, photons, electrons, light and intermediate masses, isotope production, heating and energy deposition and materials damage. Many of the experiments are associated with studies, investigations and the construction of spallation neutron sources since 1975 with emphasis on the most recent developments. The final part on technology and applications describes the various engineering problems associated with high intensity neutron spallation sources, ATW's, the needed accelerator systems, material and neutron issues, and high energy neutron source shielding aspects. A must-have for engineers and physicists working in or entering this field.

Download or read book A Proposal for a Long-pulse Spallation Source at Los Alamos National Laboratory written by and published by . This book was released on 1995 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Los Alamos National Laboratory is proposing a new spallation neutron source that will provide the US with an internationally competitive facility for neutron science and technology that can be built in approximately three years for less than $100 million. The establishment of a 1-MW, long-pulse spallation source (LPSS) at the Los Alamos Neutron Science Center (LANSCE) will meet many of the present needs of scientists in the neutron scattering community and provide a significant boost to neutron research in the US. The new facility will support the development of a future, more intense spallation neutron source, that is planned by DOE's Office of Energy Research. Together with the existing short pulse spallation source (SPSS) at the Manual Lujan, Jr. Neutron Scattering Center (MLNSC) at Los Alamos, the new LPSS will provide US scientists with a complementary pair of high-performance neutron sources to rival the world's leading facilities in Europe.

Book Synopsis Development and Applications of Negative Ion Sources by : Vadim Dudnikov
Download or read book Development and Applications of Negative Ion Sources written by Vadim Dudnikov and published by Springer Nature. This book was released on 2023-06-22 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the development of sources of negative ions and their application in science and industry. It describes the physical foundations and implementation of the key methods of negative ion production and control, such as charge exchange, thermionic emission, plasma volume, secondary emission (sputtering) and surface-plasma sources, as well as the history of their development. Following on from this essential foundational material, the book goes on to explore transport of negative ion beams, and beam-plasma instabilities. Now in its second edition, the book has been substantially expanded and updated to address the many developments since it was first published, most importantly the development and investigation of cesiated surfaces with work function ~1.2-1.3 eV in conditions close to discharges in surface plasma sources. The book also includes a new chapter on development of conversion targets for high-energy neutral beam injectors, covering gas targets, plasma targets and photon targets for efficient conversion of high energy negative ion beams to neutral beams. With exposition accessible at the graduate level, and a comprehensive bibliography, this book will appeal to all students and researchers whose work concerns ion sources and their applications to accelerators, beam physics, storage rings, cyclotrons, and plasma traps.

Book Synopsis Spin-Wave Theory and its Applications to Neutron Scattering and THz Spectroscopy by : Randy S Fishman
Download or read book Spin-Wave Theory and its Applications to Neutron Scattering and THz Spectroscopy written by Randy S Fishman and published by Morgan & Claypool Publishers. This book was released on 2018-11-05 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two of the most powerful tools used to study magnetic materials are inelastic neutron scattering and THz spectroscopy. Because the measured spectra provide a dynamical fingerprint of a magnetic material, those tools enable scientists to unravel the structure of complex magnetic states and to determine the microcscopic interactions that produce them. This book discusses the experimental techniques of inleastic neutron scattering and THz spectroscopy and provides the theoretical tools required to analyze their measurements using spin-wave theory. For most materials, this analysis can resolve the microscopic magnetic interactions such as exchange, anisotropy, and Dzyaloshinskii-Moriya interactions. Assuming a background in elementary statistical mechanics and a familiarity with the quantized harmonic oscillator, this book presents a comprehensive review of spin-wave theory and its applications to both inelastic neutron scattering and THz spectroscopy. Spin-wave theory is used to study several model magnetic systems, including non-collinear magnets such as spirals and cycloids that are produced by geometric frustration, competing exchange interactions, or Dzyaloshinskii-Moriya interactions. Several case studies utilizing spin-wave theory to analyze inelastic neutron-scattering and THz spectroscopy measurements are presented. These include both single crystals and powders and both oxides and molecule-based magnets. In addition to sketching the numerical techniques used to fit dynamical spectra based on microscopic models, this book also contains over 70 exercises that can be performed by beginning graduate students.
Book Synopsis Proceedings of the Workshop on Ion Source Issues Relevant to a Pulsed Spallation Neutron Source by :
Download or read book Proceedings of the Workshop on Ion Source Issues Relevant to a Pulsed Spallation Neutron Source written by and published by . This book was released on 1994 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: The workshop reviewed the ion-source requirements for high-power accelerator-driven spallation neutron facilities, and the performance of existing ion sources. Proposals for new facilities in the 1- to 5-MW range call for a widely differing set of ion-source requirements. For example, the source peak current requirements vary from 40 mA to 150 mA, while the duty factor ranges from 1% to 9%. Much of the workshop discussion centered on the state-of-the-art of negative hydrogen ion source (H−) technology and the present experience with Penning and volume sources. In addition, other ion source technologies, for positive ions or CW applications were reviewed. Some of these sources have been operational at existing accelerator complexes and some are in the source-development stage on test stands.
