Book Description
The symposium included 20 formal presentations on recent accomplishments in research and development for the production and neutralization of negative ions and beams. Topics include progress in technical developments and experiences, diagnostic developments, as well as in improved understanding through modeling and theoretical developments. For the first time, a simple, physics-based theoretical treatment was presented to properly model the ion extraction from negative ion sources. In addition, a method was presented that can accurately estimate the rms emittance from measured distributions. The proceedings contain all 20 presentations, written by 60 authors and co-authors, involving 21 institutions worldwide. All papers were peer reviewed.

Book Description
The Handbook of Ion Sources delivers the data needed for daily work with ion sources. It also gives information for the selection of a suitable ion source and ion production method for a specific application. The Handbook concentrates on practical aspects and introduces the principle function of ion sources. The basic plasma parameters are defined and discussed. The working principles of various ion sources are explained, and examples of each type of ion source are presented with their operational data. Tables of ion current for various elements and charge states summarize the performance of different ion sources. The problems related to the production of ions of non-gaseous elements are detailed, and data on useful materials for evaporation and ion source construction are summarized. Additional chapters are dedicated to extraction and beam formation, ion beam diagnosis, ion source electronics, and computer codes for extraction, acceleration, and beam transport. Emittance and brilliance are described and space charge effects and neutralization discussed. Various methods for the measurement of current, profile, emittance, and time structure are presented and compared. Intensity limits for these methods are provided for different ion energies. Typical problems related to the operation of ion source plasmas are discussed and practical examples of circuits are given. The influence of high voltage on ion source electronics and possibilities for circuit protection are covered. The generation of microwaves and various microwave equipment are described and special problems related to microwave operation are summarized. The Handbook of Ion Sources is a valuable reference on the subject, of benefit to practitioners and graduate students interested in accelerators, ion implantation, and ion beam techniques.

Book Description
This book describes the development of sources of negative ions and their application in science and industry. It describes the physical foundations and implementation of the key methods of negative ion production and control, such as charge exchange, thermionic emission, plasma volume, secondary emission (sputtering) and surface-plasma sources, as well as the history of their development. Following on from this essential foundational material, the book goes on to explore transport of negative ion beams, and beam-plasma instabilities. Now in its second edition, the book has been substantially expanded and updated to address the many developments since it was first published, most importantly the development and investigation of cesiated surfaces with work function ~1.2-1.3 eV in conditions close to discharges in surface plasma sources. The book also includes a new chapter on development of conversion targets for high-energy neutral beam injectors, covering gas targets, plasma targets and photon targets for efficient conversion of high energy negative ion beams to neutral beams. With exposition accessible at the graduate level, and a comprehensive bibliography, this book will appeal to all students and researchers whose work concerns ion sources and their applications to accelerators, beam physics, storage rings, cyclotrons, and plasma traps.

Book Description
This symposium addresses all aspects of H- and D- sources, the formation of negative hydrogen and deuterium beams from these sources, and their beam transport properties. The discussion includes both the latest theoretical and experimental work in these areas. The negative ion sources are multicusp, Penning, magnetron, rf (1-13 MHz), surface converter, microwave/ECR (GHz frequency), and polarized source types. Experimental work also includes beam chopping, space-charge lenses, optimized negative ion extraction systems, and beam diagnostics. The negative ion production mechanisms are volume (pure hydrogen or deuterium discharge) and surface production using cesium or other alkali metal to catalyze negative ion production. Theoretical analyses include plasma chemistry, particle-in-cell modeling, and H-/D- extraction physics simulations. The main applications for H- sources are in high-energy neutral beam injectors for fusion reactors and H- sources for charge exchange injection into synchrotrons or spallation neutron source storage rings.
