A survey of theoretical and experimental progress in the area of electron-photon interaction and dense media. This volume discusses radiation production, with descriptions of ideas and technologies that enhance the production of X-rays in the form of channelling, transition and parametric X-ray production. Progress in electron beam physics to produce sub-picosecond electron bunches from low-energy linear accelerators make it possible to produce coherent, high brightness, submillimeter radiation and sub-picosecond X-ray pulses. Micro-undulators in the form of bent crystalline structures hold promise as future X-ray sources.

A NATO Advanced Research Workshop on ”Advanced Radiation Sources and Applications” was held from August 29 to September 2, 2004. Hosted by the Yerevan Physics Institute, Yerevan, Armenia, 30 invited researchers from former Soviet Union and NATO countries gathered at Nor-Hamberd, Yerevan, on the slopes of Mount Aragats to discuss recent theoretical as well as expe- mental developments on means of producing photons from mostly low energy electrons. Thismeetingbecamepossiblethroughthegenerousfundingprovidedbythe NATO Science Committee and the programme director Dr. Fausto Pedrazzini in the NATO Scienti?c and Environmental Affairs Division. The workshop - rectors were Robert Avakian, Yerevan Physics Institute, Armenia and Helmut Wiedemann, Stanford (USA). Robert Avakian provided staff, logistics and - frastructure from the Yerevan Physics institute to assure a smooth execution of the workshop. Special thanks goes to Mrs. Ivetta Keropyan for admin- trative and logistics support to foreign visitors. The workshop was held at the institute’s resort in Nor-Hamberd on the slopes of Mount Aragats not far from the Yerevan cosmic ray station. The isolation and peaceful setting of the resort provided the background for a fruitful week of presentations and discussions. Following our invitations, 38 researchers in this ?eld came to the workshop from Armenia, Belarus, Romania, Russia, Ukraine, Denmark, France, G- many and the USA. Commuting from Yerevan local scientists joined the daily presentations. Over a ?ve day period 40 presentations were given.

A NATO Advanced Research Workshop on “Brilliant Light Facilities and Research in Life and Material Sciences” was held from July 17 to July 21, 2006. The workshop was hosted by the Center for the Advancement of Natural Discoveries using Light Emission, Yerevan - the newly established institute in Armenia with the aim to create a synchrotron radiation facility, CANDLE, as an international laboratory for advanced research in life and material sciences. About 50 researchers from NATO, partner countries and Armenia gathered at Yerevan to discuss modern trends in developments of advanced light sources with high spectral brilliance and applications in basic and applied research in a wide range of fields. Research with high brilliant photon beams are used, for example for practical applications in pharmacy, electronics and nanotechnology. Such practical relevance promoted the design and construction of now more than 50 such facilities worldwide. Overview and specialized talks on the status and highlights of newly constructed light sources (ALBA, SPEAR3, European XFEL Facility, Siberian Synchrotron Radiation Center, CANDLE), on instrumentation and development of experimental techniques, and frontier research in life and material sciences using synchrotron radiation have been presented. More than 60% of the program was devoted to application of synchrotron radiation in biophysics, biochemistry, biomedicine, material and environmental investigations. The workshop brought together scientists from a wide spectrum of research fields emphasizing the wide application and demand of synchrotron radiation and underlining the necessity of user involvement in the early design stages of a new project.

Part III is an extensive primer in beam dynamics, followed, in Part IV, by an introduction and description of the main beam parameters and including a new chapter on beam emittance and lattice design.

This book by Helmut Wiedemann is a well-established, classic text, providing an in-depth and comprehensive introduction to the field of high-energy particle acceleration and beam dynamics.The present 4th edition has been significantly revised, updated and expanded. The newly conceived Part I is an elementary introduction to the subject matter for undergraduate students. Part II gathers the basic tools in preparation of a more advanced treatment, summarizing the essentials of electrostatics and electrodynamics as well as of particle dynamics in electromagnetic fields. Part III is an extensive primer in beam dynamics, followed, in Part IV, by an introduction and description of the main beam parameters and including a new chapter on beam emittance and lattice design. Part V is devoted to the treatment of perturbations in beam dynamics. Part VI then discusses the details of charged particle acceleration. Parts VII and VIII introduce the more advanced topics of coupled beam dynamics and describe very intense beams – a number of additional beam instabilities are introduced and reviewed in this new edition. Part IX is an exhaustive treatment of radiation from accelerated charges and introduces important sources of coherent radiation such as synchrotrons and free-electron lasers. The appendices at the end of the book gather useful mathematical and physical formulae, parameters and units. Solutions to many end-of-chapter problems are given.This textbook is suitable for an intensive two-semester course starting at the senior undergraduate level.

In this book the characteristics of synchrotron radiation, including insertion device radiation, are described and derived from first principles. The reader is first introduced to the subject in an intuitive way in order to gain familiarity with the underlying physical processes. A rigorous mathematical derivation of the theory then follows. Since the characteristics of synchrotron radiation are intimately connected with the parameters of the electron beam and its accelerator, a basic introduction to electron beam dynamics and accelerator design is included. The book is aimed at graduate students and scientists working with synchrotron radiation and is designed to serve both as a textbook and as a reference work. It includes numerous exercises, some with solutions.
