This book was released on 2004 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The explosion of deuterated clusters heated by ultra short, high intense laser pulses provides ions with sufficient energy to undergo fusion reactions. Based on this mechanism monochromatic dd-fusion neutrons can be produced by illuminating deuterium clusters with a high intensity laser. For the work presented in this thesis we employed such a cluster fusion neutron source. The clusters from a cryogenically cooled gas jet were heated with a femtosecond, terawatt class Ti:sapphire laser. The results presented in this thesis fall into three categories. First general features of the neutron source will be discussed including the energy dependence and the angular dependence of the neutron source. Then as a first application of the source the calibration of a neutron detector for single shot dd-fusion experiments will be presented. Finally magnetic confinement as a method for increasing the neutron yield will be discussed.

This book was released on 2016 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: A team of Los Alamos researchers supported a final campaign to use the Trident laser to produce neutrons, contributed their multidisciplinary expertise to experimentally assess if laser-driven neutron sources can be useful for MaRIE. MaRIE is the Laboratory's proposed experimental facility for the study of matter-radiation interactions in extremes. Neutrons provide a radiographic probe that is complementary to x-rays and protons, and can address imaging challenges not amenable to those beams. The team's efforts characterize the Laboratory's responsiveness, flexibility, and ability to apply diverse expertise where needed to perform successful complex experiments.

Download or read book Assessment of Laser Driven Pulsed Neutron Sources for Poolside Neutron based Advanced NDE A Pathway to LANSCE like Characterization at INL written by and published by . This book was released on 2017 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: A variety of opportunities for characterization of fresh nuclear fuels using thermal (~25meV) and epithermal (~10eV) neutrons have been documented at Los Alamos National Laboratory. They include spatially resolved non-destructive characterization of features, isotopic enrichment, chemical heterogeneity and stoichiometry. The LANSCE spallation neutron source is well suited in neutron fluence and temporal characteristics for studies of fuels. However, recent advances in high power short pulse lasers suggest that compact neutron sources might, over the next decade, become viable at a price point that would permit their consideration for poolside characterization on site at irradiation facilities. In a laser-driven neutron source the laser is used to accelerate deuterium ions into a beryllium target where neutrons are produced. At this time, the technology is new and their total neutron production is approximately four orders of magnitude less than a facility like LANSCE. However, recent measurements on a sub-optimized system demonstrated>1010 neutrons in sub-nanosecond pulses in predominantly forward direction. The compactness of the target system compared to a spallation target may allow exchanging the target during a measurement to e.g. characterize a highly radioactive sample with thermal, epithermal, and fast neutrons as well as hard X-rays, thus avoiding sample handling. At this time several groups are working on laser-driven neutron production and are advancing concepts for lasers, laser targets, and optimized neutron target/moderator systems. Advances in performance sufficient to enable poolside fuels characterization with LANSCE-like fluence on sample within a decade may be possible. This report describes the underlying physics and state-of-the-art of the laser-driven neutron production process from the perspective of the DOE/NE mission. It also discusses the development and understanding that will be necessary to provide customized capability for characterization of irradiated fuels. Potential operational advantages compared to a spallation neutron source include reduced shielding complexity, reduced energy requirements, and a production target free of fission products. Contributors to this report include experts in laser-driven neutron production (Roth, Fernandez), laser design (Haefner, Siders, Leemans), laser target design (Glenzer), spallation target/moderator design (Mocko), neutron instrumentation and characterization applications (Vogel, Bourke).

This book was released on 2003-05-11 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent scientific and technical advances have made it possible to create matter in the laboratory under conditions relevant to astrophysical systems such as supernovae and black holes. These advances will also benefit inertial confinement fusion research and the nation's nuclear weapon's program. The report describes the major research facilities on which such high energy density conditions can be achieved and lists a number of key scientific questions about high energy density physics that can be addressed by this research. Several recommendations are presented that would facilitate the development of a comprehensive strategy for realizing these research opportunities.

Available in PDF, EPUB and Kindle. Book excerpt: As part of the Physics 2010 decadal survey project, the Department of Energy and the National Science Foundation requested that the National Research Council assess the opportunities, over roughly the next decade, in atomic, molecular, and optical (AMO) science and technology. In particular, the National Research Council was asked to cover the state of AMO science, emphasizing recent accomplishments and identifying new and compelling scientific questions. Controlling the Quantum World, discusses both the roles and challenges for AMO science in instrumentation; scientific research near absolute zero; development of extremely intense x-ray and laser sources; exploration and control of molecular processes; photonics at the nanoscale level; and development of quantum information technology. This book also offers an assessment of and recommendations about critical issues concerning maintaining U.S. leadership in AMO science and technology.

This book was released on 2008-03-17 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structural analysis is becoming increasingly important for the design of novel, advanced engineering materials, components and assemblies. By using the neutrons and synchrotron radiation, information about the micro- and nanostructure of materials can be obtained non-destructively and with high spatial reolution, both in the near-surface region an also in the bulk of samples and components. Besides its coverage of synchrotron and neutron sources, materials and material processes, measuring techniques, and applications, this ready reference both important method types: diffraction and tomography. Following an introduction, a general section leads on to methods, while further sections are devoted to emerging methods an industrial applications. In this way, the text provides new users of large-scale facilities with easy access to an understanding of both the methods and opportunities offered by different sources and instruments.
