Book Description
A neutral particle analyzer was engineered specifically for inertial electrostatic confinement (IEC) fusion devices for the first time and particularly for studies with relevance to operation with helium-3, an advanced fusion fuel. For experiments with helium, this technique yields energy distributions of escaping fast neutral particles produced by atomic and molecular processes between energetic ions and background gas, as well as the line-of-sight-averaged energy distributions of fast ions. The setup uses a 10 nm carbon foil as a stripping target for incident fast neutral particles and cylindrical electrodes with a variable relative voltage for deflecting ions of a specific energy per unit charge into a continuous electron multiplier. The new diagnostic can be used to study neutral particles with kinetic energies between 5 and 170 keV, with a measured energy resolution of 2-4% between 5 and 30 keV. Initial neutral particle analysis experiments have been performed at cathode voltages up to 60 kV for IEC devices in the glow discharge, external-ion-source and filament-assisted source plasma configurations, with both helium-4 and deuterium gas. Comparisons between experimentally determined neutral-particle energy distributions and predictions by the VICTER and HeVICTER integral-transport numerical codes on spherically convergent ion flow in IEC devices show that the codes do not capture many details of the relevant physics. For helium-4 experiments in the external-ion-source mode, the energy distributions were confirmed to be significantly harder at 0.2 millitorr than at 5 millitorr, which is essential for the prospects of the configuration for increasing helium-3 fusion rates.
Nuclear Fusion by Inertial Confinement

Pages : 784
Book Description
Nuclear Fusion by Inertial Confinement provides a comprehensive analysis of directly driven inertial confinement fusion. All important aspects of the process are covered, including scientific considerations that support the concept, lasers and particle beams as drivers, target fabrication, analytical and numerical calculations, and materials and engineering considerations. Authors from Australia, Germany, Italy, Japan, Russia, Spain, and the U.S. have contributed to the volume, making it an internationally significant work for all scientists working in the Inertial Confinement Fusion (ICF) field, as well as for graduate students in engineering and physics with interest in ICF.
Controlled Fusion
Author: John KilleenPublisher: Elsevier
ISBN: 0323149367
Category : Science
Languages : en
Pages : 465
Book Description
Methods in Computational Physics, Volume 16: Controlled Fusion considers the full variety of computer models needed for the simulation of realistic fusion devices. These computer models include time-dependent magnetohydrodynamics, plasma transport in a magnetic field, MHD and guiding-center equilibria, MHD stability of confinement systems, Vlasov and particle models, and multispecies Fokker-Planck codes. This volume is divided into 11 chapters. The first three chapters discuss various aspects of the numerical solution of the equations of magnetohydrodynamics (MHD). The subsequent chapters present the more realistic models, including the thermal conductivity and electrical resistivity. Other chapters describe two-dimensional codes with varies choice of coordinate systems, such as fixed Eulerian grid, Lagrangian descriptions, and the use of magnetic flux surfaces as coordinate surfaces. The discussion then shifts to models on the inclusion of neutrals and impurities, as well as the use of empirical transport coefficients. A chapter surveys the development of time-dependent codes to support the design and operation of major CTR experiment. The final chapters explore the electromagnetic codes in the nonradiative limit (Darwin model) where the equations are nonrelativistic and displacement currents are neglected. This book is an invaluable source for geoscientists, physicists, and mathematicians.

An Introduction to Inertial Confinement Fusion

Pages : 244
Book Description
Newcomers to the field of inertial confinement fusion (ICF) often have difficulty establishing a clear picture of the overall field. The reason for this is because, while there are many books devoted to special topics within the field, there is none that provides an overview of the field as a whole.
