Book excerpt: Since the earliest days of fusion research it has been hoped that diamagnetic currents flowing in a plasma could be used to help confine the plasma. Recently this hope has been strengthened both by theoretical advances and by experimental results made possible by technological developments. On the theoretical front analytical treatments and computer simulation studies have demonstrated equilibrium solutions existing both in the fluid limit and in the large-orbit limit. Progress has also been made in determining the conditions required for the stability of field-reversed entities. It appears that configurations of the general form of fat doughnuts, possibly elongated to napkin-ring form, represent stable states. Building on previous experimental work, several investigators have been able to create field-reversed states. One method, based on the ASTRON idea of Christofilos, traps an intense relativistic electron beams (REB) to create a field-reversing current ring. Other approaches use either the reversed field theta pinch technique or REB pulses to create field-reversing diamagnetic currents in a long cylindrical plasma. In the former method, millisecond-long field-reversing electron rings have been achieved; in the latter method field-reversed plasma states lasting 30 to 50 microseconds have been achieved. Another approach under investigation is the Field Reversed Mirror (FRM) created by the tangential injection of high current neutral beams. Plasma states that approach field reversal have been achieved by this technique.

Book excerpt: This report discusses some of the physics issues anticipated in field-reversed mirrors. The effect of current cancellation due to electrons is described. An estimate is made of the required impurity level to maintain a field-reversed configuration. The SUPERLAYER code is used to simulate the high-.beta. 2XIIB results, and favorable comparisons require inclusion of quasilinear RF turbulence. Impact of a quadrupole field on field-line closure and resonant transport is discussed. A simple self-consistent model of ion currents is presented. Conditions for stability of field-reversed configurations to E x B driven rotations are determined.

Available in PDF, EPUB and Kindle. Book excerpt: These proceedings cover the lectures delivered at the Fifth International Summer College on Physics and Contemporary Needs from June 16-July 4, 1980 at Nathiagali, one of the scenic hill resorts in the northern part of Pakistan. The college was organized by the Pakistan Atomic Energy Commission (PAEC) and co-sponsored by the International Centre for Theroetical Physics (ICTP), Trieste, Italy. It also received a financial grant from the University Grants Commission (UGC) for the participation of physicists from various universities in Pakistan. The college was attended by 22 lecturers and invited seminar speakers, 150 participants from 30 countries, and consisted of 15 concentrated days of lectures, seminars and informal discussions. These proceedings contain only some of the regular lectures delivered at Nathiagali, but the seminars heldthere are listed in the Appendix. This year the main emphasis of the college was on the fron tiers of physics, particularly on the recent exciting development in high-energy physics and astrophysics. However, the lectures delivered at the college also covered a large sample of other aspects of physics ranging from low"-temperature physics to plasma physics of of fusion. The series of colleges of which the present college is the fifth, an attempt to remove the barrier of isolation for the physicists working in developing countries, far removed from active centres of research. It is hoped that these colleges are helping to fill the gap in communication between the physicists of developing and advanced countries.

Book excerpt: The stability of the field-reversed mirror configuration to acoustic modes in the low-frequency regime is analyzed. While previous work has been done using field-reversed configurations in the geometrical limit of infinite length, or zero plasma width, the attempt here is to analyze an equilibrium that has order unity aspect ratio. Further, while previous efforts have concentrated on fluid equilibrium or a specific distribution function, the approach here is to develop a formalism that can be used for an arbitrary distribution that is a function of the constants of motion.

Available in PDF, EPUB and Kindle. Book excerpt: Driven Magnetic Fusion Reactors is a collection of papers from the Proceedings of the Course held in Erice-Trapani, Italy on September 18-26, 1978. This collection describes the reactor aspects, the devices, physics, and the common technologies of the ""mirrors"" and the ""two component Tokamaks"" approach. This book reviews the mirror approach, which is used in the magnetic fusion energy program in the U.S. This program focuses on the tandem mirror and field reversed mirror concepts. This book explains the physics of field reversed mirrors and the mirror fusion test facility. The mirror machine as capable of producing fusion reaction with many advantages compared to the mainline tokamak is also discussed. The text also describes other ways to construct a fusion reactor by using a small quantity of quadrupole minimum-B mirrors that are linked toroidally to form a closed-line containment system. This book then presents methods of operating a driven tokamak reactor using the beam heated tokamak BHT, the two-component TCT, and the hot ion tokamak. This collection also describes the roles of low-Q fusion devices, and that of the fission-fusion hybrid version. This text addresses the non-electrical applications of the fusion process that is being done in the U.S. Then this collection also discusses a global approach to the fuel cycles and the different energy strategies of the U.S., Europe, and Japan. This book addresses the many interests of nuclear physicists, nuclear engineers, scientists, students, and academicians in the field of advanced physics.
