Final Report of the Committee on a Strategic Plan for U.S. Burning Plasma Research

Book Description
Fusion offers the prospect of virtually unlimited energy. The United States and many nations around the world have made enormous progress toward achieving fusion energy. With ITER scheduled to go online within a decade and demonstrate controlled fusion ten years later, now is the right time for the United States to develop plans to benefit from its investment in burning plasma research and take steps to develop fusion electricity for the nation's future energy needs. At the request of the Department of Energy, the National Academies of Sciences, Engineering, and Medicine organized a committee to develop a strategic plan for U.S. fusion research. The final report's two main recommendations are: (1) The United States should remain an ITER partner as the most cost-effective way to gain experience with a burning plasma at the scale of a power plant. (2) The United States should start a national program of accompanying research and technology leading to the construction of a compact pilot plant that produces electricity from fusion at the lowest possible capital cost.
Active Control of Magneto-hydrodynamic Instabilities in Hot Plasmas

Book Description
During the past century, world-wide energy consumption has risen dramatically, which leads to a quest for new energy sources. Fusion of hydrogen atoms in hot plasmas is an attractive approach to solve the energy problem, with abundant fuel, inherent safety and no long-lived radioactivity. However, one of the limits on plasma performance is due to the various classes of magneto-hydrodynamic instabilities that may occur. The physics and control of these instabilities in modern magnetic confinement fusion devices is the subject of this book. Written by foremost experts, the contributions will provide valuable reference and up-to-date research reviews for "old hands" and newcomers alike.

Book Description
Magnetic Fusion Energy: From Experiments to Power Plants is a timely exploration of the field, giving readers an understanding of the experiments that brought us to the threshold of the ITER era, as well as the physics and technology research needed to take us beyond ITER to commercial fusion power plants. With the start of ITER construction, the world's magnetic fusion energy (MFE) enterprise has begun a new era. The ITER scientific and technical (S&T) basis is the result of research on many fusion plasma physics experiments over a period of decades. Besides ITER, the scope of fusion research must be broadened to create the S&T basis for practical fusion power plants, systems that will continuously convert the energy released from a burning plasma to usable electricity, operating for years with only occasional interruptions for scheduled maintenance. - Provides researchers in academia and industry with an authoritative overview of the significant fusion energy experiments - Considers the pathway towards future development of magnetic fusion energy power plants - Contains experts contributions from editors and others who are well known in the field

Book Description
Recent MHD calculations predict that, for a plasma with sufficient rotation, a resistive wall can provide stability up to the [beta]{sub N} limit predicted assuming the wall were ideal. In the region of [beta]{sub N} between the wall-at-infinity limit and the ideal-wall limit, an MHD instability branches into two modes: a plasma mode, that is nearly stationary with respect to the plasma at the resonant surface, and a resistive wall mode (RWM), that is nearly stationary with respect to the wall. Experiments conducted in the DIII-D, PBX-M and HBT-EP tokamaks have demonstrated that plasmas with a nearby conducting wall can remain stable above the beta limit predicted with wall-at-infinity, and have reported observations of instabilities with the characteristics of a resistive wall mode. In the experiments described in this paper, improved diagnostic measurements and plasma operational techniques, giving broader current density profiles and high toroidal rotation, have provided direct identification of the resistive wall mode. These experiments were designed to ease the requirements on total beta in favor of maximizing the wall stability enhancement factor, E{sub W}, increasing the duration of the wall-stabilized phase, and ensuring shot-to-shot reproducibility with the available heating power.
