Download or read book Design, Operational Experiences and Beam Results Obtained with the SNS H- Ion Source and LEBT at Berkeley Lab written by and published by . This book was released on 2002 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ion source and Low-Energy Transport (LEBT) system that will provide H− ion beams to the Spallation Neutron Source (SNS)** Front End and the accelerator chain have been developed into a mature unit that fully satisfies the operational requirements through the commissioning and early operating phases of SNS. Compared to the early R & D version, many features of the ion source have been improved, and reliable operation at 6% duty factor has been achieved producing beam currents in the 35-mA range and above. LEBT operation proved that the purely electrostatic focusing principle is well suited to inject the ion beam into the RFQ accelerator, including the steering and pre-chopping functions. This paper will discuss the latest design features of the ion source and LEBT, give performance data for the integrated system, and report on commissioning results obtained with the SNS RFQ and Medium-Energy Beam Transport (MEBT) system. Prospects for further improvements will be outlined in concluding remarks.

Book Synopsis Production and Neutralization of Negative Ions and Beams by : Joseph D. Sherman
Download or read book Production and Neutralization of Negative Ions and Beams written by Joseph D. Sherman and published by American Institute of Physics. This book was released on 2005-04-20 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: We consider the requirements and constraints for negative-ion-based neutral beam injection systems, and show how these are reflected in design considerations. We will attempt to develop a set of guidelines for users and developers to use to see how well (in a qualitative sense, at least) a particular neutral beam system fits a particular proposed need.

Book excerpt: This book comprises selected proceedings of the ThEC15 conference. The book presents research findings on various facets of thorium energy, including exploration and mining, thermo-physical and chemical properties of fuels, reactor physics, challenges in fuel fabrication, thorium fuel cycles, thermal hydraulics and safety, material challenges, irradiation experiences, and issues and challenges for the design of advanced thorium fueled reactors. Thorium is more abundant than uranium and has the potential to provide energy to the world for centuries if used in a closed fuel cycle. As such, technologies for using thorium for power generation in nuclear reactors are being developed worldwide. Since there is a strong global thrust towards designing nuclear reactors with thorium-based fuel, this book will be of particular interest to nuclear scientists, reactor designers, regulators, academics and policymakers.
