Download Development and Applications of Negative Ion Sources Book in PDF, ePub and Kindle
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, 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. 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.

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.

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.

The reported advances with small sources of negative ions, especially negative hydrogen ions, drive the progress of many accelerators and enable new research methods and technologies. Large sources of negative deuterium ions are being developed for the international experimental fusion reactor (ITER) that will require 40 MW of plasma heating. The developments increasingly use computer modeling to understand the underlying physics, improve existing, and develop new technologies.

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.

Download Design Considerations for a Negative Ion Source for Dc Operation of High-power, Multi-megaelectron-volt Neutral Beams Book in PDF, ePub and Kindle
A dc negative hydrogen and/or deuterium ion source is needed to prouce high-power, high-energy neutral beams for alpha diagnostics and current drive applicatiosn in fusion devices. The favorable beam particle energy for such applications extends to 1.5 MeV/amu. Continuous-wave (cw) radio-frequency quadrupole (RFQ) accelerators have been proposed to accelerate negative ions effeciently to this energy range. In this paper, the desired beam properties for ion beams injected into cw RFQ accelerators are summariezed. A number of candidate ion sources being developed at Culham, JAERI, LBL, and ORNL may prove useful for these applications. The properties of the Volume Ionization with Transverse Extraction (VITEX) ion sources being developed at ORNL are presented. Scaling such a dc ion source to produce ampere beams is discussed. 53 refs., 4 figs., 2 tabs.
