Available in PDF, EPUB and Kindle. Book excerpt: X-Ray and Neutron Diffraction describes the developments of the X-ray and the various research done in neutron diffraction. Part I of the book concerns the principles and applications of the X-ray and neutrons through their origins from classical crystallography. The book explains the use of diffraction methods to show the highly regular arrangement of atoms that forms a continuous pattern in three-dimensional space. The text evaluates the limitations and benefits of using the different types of radiation sources, whether these are X-rays, neutrons, or electrons. Part II is a collection of reprints discussing the development of techniques that includes a modification of the Bragg method, which is a method of X-ray crystal analysis. One paper presents an improved numerical method of two-dimensional Fourier synthesis for crystals. This method uses a greatly reduced process of arrangement of sets of figures found in the two-dimensional Fourier series. The book also notes the theoretical considerations and the practical details, and then addresses precautions against possible inclusions of errors in this method. The text deals as well with the magnetic scattering of neutrons, and one paper presents a simple method of gathering information about the magnetic moment of the neutron besides the traditional Stern-Gerlach method. Nuclear scientists and physicists, atomic researchers, and nuclear engineers will greatly appreciate the book.
Download or read book Physics Fabrication and Applications of Multilayered Structures written by Claude Weisbuch and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-dimensional materials are of fundamental interest in physics and chemistry and have also found a wide variety of technological applica tions in fields ranging from microelectronics to optics. Since 1986, several seminars and summer schools devoted to low-dimensional systems have been supported by NATO. The present one, Physics, Fabrication and Applications of Multilayered structures, brought together specialists from different fields in order to review fabrication techniques, charac terization methods, physics and applications. Artificially layered materials are attractive because alternately layering two (or more) elements, by evaporation or sputtering, is a way to obtain new materials with (hopefully) new physical properties that pure materials or alloys do not allow. These new possibilities can be ob tained in electronic transport, optics, magnetism or the reflectivity of x-rays and slow neutrons. By changing the components and the thickness of the layers one can track continuously how the new properties appear and follow the importance of the multilayer structure of the materials. In addition, with their large number of interfaces the study of inter face properties becomes easier in multilayered structures than in mono layers or bilayers. As a rule, the role of the interface quality, and also the coupling between layers, increases as the thickness of the layer decreases. Several applications at the development stage require layer thicknesses of just a few atomic layers.

Available in PDF, EPUB and Kindle. Book excerpt: Volume 63 of Reviews in Mineralogy and Geochemistry provides an introduction for those not yet familiar with neutrons by describing basic features of neutrons and their interaction with matter as well illustrating important applications. The volume is divided into 17 Chapters. The first two chapters introduce properties of neutrons and neutron facilities, setting the stage for applications. Some applications rely on single crystals (Chapter 3) but mostly powders (Chapters 4-5) and bulk polycrystals (Chapters 15-16) are analyzed, at ambient conditions as well as low and high temperature and high pressure (Chapters 7-9). Characterization of magnetic structures remains a core application of neutron scattering (Chapter 6). The analysis of neutron data is not trivial and crystallographic methods have been modified to take account of the complexities, such as the Rietveld technique (Chapter 4) and the pair distribution function (Chapter 11). Information is not only obtained about solids but about liquids, melts and aqueous solutions as well (Chapters 11-13). In fact this field, approached with inelastic scattering (Chapter 10) and small angle scattering (Chapter 13) is opening unprecedented opportunities for earth sciences. Small angle scattering also contributes information about microstructures (Chapter 14). Neutron diffraction has become a favorite method to quantify residual stresses in deformed materials (Chapter 16) as well as preferred orientation patterns (Chapter 15). The volume concludes with a short introduction into neutron tomography and radiography that may well emerge as a principal application of neutron scattering in the future (Chapter 17).

Download or read book Neutron Scattering written by and published by Academic Press. This book was released on 2013-11-22 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work covers in some detail the application of neutron scattering to different fields of physics, materials science, chemistry, biology, the earth sciences and engineering. Its goal is to enable researchers in a particular area to identify aspects of their work in which neutron scattering techniques might contribute, conceive the important experiments to be done, assess what is required to carry them out, write a successful proposal for one of the major user facilities, and perform the experiments under the guidance of the appropriate instrument scientist. The authors of the various chapters take account of the advances in experimental techniques over the past 25 years--for example, neutron reflectivity and spin-echo spectroscopy and techniques for probing the dynamics of complex materials and biological systems. Furthermore, with the third-generation spallation sources recently constructed in the United States and Japan and in the advanced planning stage in Europe, there is an increasing interest in time-of-flight techniques and short wavelengths. Correspondingly, the improved performance of cold moderators at both reactors and spallation sources has extended the long-wavelength capabilities. - Chapter authors are pre-eminent in their field - Seminal experiments are presented as examples - Provides guidance on how to plan, execute and analyse experiments

Download or read book Target Station Optimization for the High Brilliance Neutron Source HBS written by Jan Philipp Dabruck and published by Springer. This book was released on 2018-12-29 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the present work, the target station of the accelerator-driven neutron source HBS is optimized in comprehensive parameter studies using the Monto-Carlo method. The dependence of the most important performance characteristics of such a system on the external parameters is investigated neglecting technical and mechanical limitations. In this way, qualitative and quantitative statements for all possible configurations and envisaged applications can be derived and should be considered in the detailed planning of such facilities. For this purpose, different scenarios are considered that place completely different requirements on the design of the target station. The central statements derived in this thesis can be transferred to any framework conditions, such as different accelerator energies, so that these results can be used in the development of other neutron sources, which together with the HBS form a European network and provide a prosperous community in neutron science.

Book excerpt: New Directions in Physics represents a fascinating view of the future as seen by some of the remarkable men who were here over 40 years ago. It makes it quite clear that we are still in the dawn of physics—the excitement and challenge that lie ahead are extraordinary. We also get a glimpse of where these remarkable men have been since the end of Project Y of the Manhattan Project and where they see the future directions for physics. This book comprises 20 chapters, with the first being an introductory chapter describing Los Alamos in the 1980s. The following chapters go on to discuss tiny computers obeying quantum mechanical laws; the past, present, and future of nuclear magnetic resonance; and experimental evidence that an asteroid impact led to the extinction of many species 65 million years ago. Other chapters cover the lunar laboratory; the future of particle accelerators; models, hypotheses and approximations; and comments on three thermonuclear paths for the synthesis of helium. The book also describes how the sad augurs mock their own presage; experiments on time reversal symmetry and parity; the course of our magnetic fusion energy enterprise; early days in the Lawrence Laboratory; nuclear charge distribution in fission; developing larger software systems; reflections on style in physics; tuning up the TPC; remarks on the future of particle physics; the supernova theory; and the history and hierarchy of structure. This book will be of interest to practitioners in the field of theoretical physics.
Download or read book Progress in Neutron Capture Therapy for Cancer written by B.J. Allen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the many advances made in the diagnosis and therapy of cancer, the mortality rate is still about half that of the incidence rate. However, the odds are not evenly distributed. Prognosis for some cancers is good, but for others, few patients will survive 12 months. This latter group of cancers is characterised by a proclivity to disseminate malignant cells in the host organ. The degree of surgery possible may be limited by the critical nature of the organ, and chemotherapy and radiotherapy are of palliative value only. In some cases systemic metastases occur, but in other cases, failure to achieve local control results in death. First among these cancers are the high grade brain tumours, astrocytoma 3,4 and glioblastoma multiforme. Local control of these tumours should lead to cure. Other cancers melanoma metastatic to the brain, for which a useful palliative therapy is not yet available, and pancreatic cancer for which localised control at an early stage could bring about improved prognosis. Patients with these cancers have little grounds for hope. Our primary objective is to reverse this situation with Neutron Capture Therapy (NCT). The purpose of this fourth symposium is to hasten the day whereby patients with these cancers can reasonably hope for substantial remissions. The first symposium on NCT was held in Boston in 1983, followed by Tokyo in 1985 and Bremen, Germany in 1988.
