Techniques In High Pressure Neutron Scattering

Drawing on the author’s practical work from the last 20 years, Techniques in High Pressure Neutron Scattering is one of the first books to gather recent methods that allow neutron scattering well beyond 10 GPa. The author shows how neutron scattering has to be adapted to the pressure range and type of measurement. Suitable for both newcomers and experienced high pressure scientists and engineers, the book describes various solutions spanning two to three orders of magnitude in pressure that have emerged in the past three decades. Many engineering concepts are illustrated through examples of real high pressure devices that have demonstrated their capacity and have produced scientific results. After introducing basic engineering concepts related to the elastic and plastic behavior of cylindrical pressure devices, the text emphasizes mechanical and neutronic properties of construction materials. Subsequent chapters describe numerous high pressure techniques, including liquid/gas, clamp, and McWhan cells. The book also focuses on Paris-Edinburgh devices, high pressure metrology, and scientific applications.

Neutron scattering experiments determine the atomic and/or magnetic structure of a material. Neutron scattering as an experimental technique is used in crystallography, physics, physical chemistry, biophysics, and materials research. It is practiced at research reactors and spallation neutron sources that provide neutron radiation of sufficient intensity. Neutron diffraction (elastic scattering) is used for determining structures; inelastic neutron scattering is used for the study of atomic vibrations and other excitations. It is the ideal method to study a wide range of important and common materials like ice and ammonia. Knowledge of the positions of the atoms in systems like these when they are compressed helps our understanding of topics as diverse as the behavior of proteins and the origins of the magnetic fields of planets like Uranus and Neptune. Until 1990, neutron diffraction was limited to pressures below 30,000 atmospheres. This was a very low pressure when compared to other structural techniques like x-ray diffraction and light-scattering which at that time were achieving pressures in excess of 1 million atmospheres. Amongst the broad suite of scattering tools available today, neutrons provide unique capabilities of fundamental importance. However, to date, the growth of neutron scattering under extremes of pressure has been limited by the weakness of available sources. In recent years, extensive investments have led to the construction of a new generation of neutron sources while existing facilities have been revitalized by upgrades. It has increased the pressure range for neutron scattering by a factor of ten with the development of a novel large volume pressure cell. Techniques in High Pressure Neutron Scattering presents contemporary methods and techniques that allow neutron scattering well beyond 10 GPa. It demonstrates how high pressure neutron scattering can be used to study the structure and dynamics of a wide range of materials. It will be of pertinent for newcomers and experienced high pressure scientists and engineers, researchers and practitioners, as well as advanced graduate students.

Neutron Scattering - Magnetic and Quantum Phenomena provides detailed coverage of the application of neutron scattering in condensed matter research. The book's primary aim is to enable researchers in a particular area to identify the aspects of their work where 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. An earlier series edited by Kurt Sköld and David L. Price, and published in the 1980s by Academic Press as three volumes in the series Methods of Experimental Physics, was very successful and remained the standard reference in the field for several years. This present work has similar goals, taking into account the advances in experimental techniques over the past quarter-century, for example, neutron reflectivity and spin-echo spectroscopy, and techniques for probing the dynamics of complex materials of technological relevance. This volume complements Price and Fernandez-Alonso (Eds.), Neutron Scattering - Fundamentals published in November 2013. Covers the application of neutron scattering techniques in the study of quantum and magnetic phenomena, including superconductivity, multiferroics, and nanomagnetism Presents up-to-date reviews of recent results, aimed at enabling the reader to identify new opportunities and plan neutron scattering experiments in their own field Provides a good balance between theory and experimental techniques Provides a complement to Price and Fernandez-Alonso (Eds.), Neutron Scattering - Fundamentals published in November 2013

Neutron Scattering: Applications in Chemistry, Materials Science and Biology, Volume 49, provides an in-depth overview of the applications of neutron scattering in the fields of physics, materials science, chemistry, biology, the earth sciences, and engineering. The book describes the tremendous advances in instrumental, experimental, and computational techniques over the past quarter-century. Examples include the coming-of-age of neutron reflectivity and spin-echo spectroscopy, the advent of brighter accelerator-based neutron facilities and associated techniques in the United States and Japan over the past decade, and current efforts in Europe to develop long-pulse, ultra-intense spallation neutron sources. It acts as a complement to two earlier volumes in the Experimental Methods in the Physical Science series, Neutron Scattering: Fundamentals(Elsevier 2013) and Neutron Scattering: Magnetic and Quantum Phenomena (Elsevier 2015). As a whole, the set enables researchers to identify aspects of their work where neutron scattering techniques might contribute, conceive the important experiments to be done, assess what is required, write a successful proposal for one of the major facilities around the globe, and perform the experiments under the guidance of the appropriate instrument scientist. Completes a three-volume set, providing extensive coverage on emerging and highly topical applications of neutron scattering Addresses the increasing use of neutrons by chemists, life scientists, material scientists, and condensed-matter physicists Presents up-to-date reviews of recent results, enabling readers to identify new opportunities and plan neutron scattering experiments in their own field

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).

This book provides ideas on what neutron scattering could look like in the next millennium. In particular, nonconventional, unusual or innovative neutron scattering experiments (from both the scientific and the instrumental point of view) are described which either have novel applications or provide a new insight into science and technology. Chapters on theoretical aspects are adequately included. The scientific and technical areas cover the following topics: novel neutron scattering techniques and perspectives in neutron scattering instrumentation (including sample environment); soft condensed matter, particularly colloids and polymers; materials science and industrial applications; structure and dynamics of multilayers and nanocrystalline materials; dynamical aspects and quantum effects in molecular magnets; strongly correlated electron systems, with emphasis on dynamic correlations in low-dimensional magnets. All these topics are thoroughly introduced and discussed by acknowledged experts.
