An Introduction to Synchrotron Radiation
John Wiley & Sons Inc (Verlag)
978-1-119-28039-2 (ISBN)
Synchrotron light is recognized as an invaluable research tool by a broad spectrum of scientists, ranging from physicists to biologists and archaeologists. The comprehensively revised second edition of An Introduction to Synchrotron Radiation offers a guide to the basic concepts of the generation and manipulation of synchrotron light, its interaction with matter and the application of synchrotron light in x-ray scattering, spectroscopy, and imaging.
The author, a noted expert in the field, reviews the fundamentals of important experimental methods, and explores the most recent technological advances in both the latest generation of x-ray sources and x-ray instrumentation. Designed to be an accessible resource, the book contains full-colour illustrations of the underlying physics and experimental applications, as well as the most commonly-used synchrotron techniques. In particular, the updated second edition now includes:
In-depth descriptions of the latest x-ray-source technologies, notably diffraction-limited storage rings and x-ray free-electron lasers
The latest advances in instrumentation, x-ray optics, and experimental methods in synchrotron radiation
The most recent developments in macromolecular crystallography, time-resolved studies, and imaging techniques
A comprehensive set of problems for each chapter, plus their ideal solutions in the appendices.
Written for undergraduate and postgraduate students from all areas of the natural and physical sciences, An Introduction to Synchrotron Radiation, Second Edition is an invaluable up-to-date reference source in this highly multidisciplinary field.
PowerPoint slides of all the figures within the text are available for download, for instructors and users of this book, at http://booksupport.wiley.com
Philip Willmott is the Project Leader of the upgrade to DLSR status of the Swiss Light Source at the Paul Scherrer Institute. He has taught elective courses in surface science and laser physics, and presently regularly offers introductory courses in synchrotron science and techniques, including, most recently, an online Massive Open Online Course (MOOC) based on the contents of this text. He is a titular professor in the Physics Institute of Zurich University and a physicist with over 25 years' experience in diverse aspects of experimental physics and materials science.
