Book excerpt: In a previous report, it was explained how it is desirable to maximize the amount of power that can be transmitted from a reentry vehicle by suppressing the onset of antenna voltage breakdown. Thus, the amount of high power EM radiation that can be transmitted will be greatly enhanced if electrophilic compounds are injected into the reentry flow field. A computer program has been set up and is now capable of numerically integrating Maxwell's equations coupled with the plasma transport equations. The computer code calculates the electron density profile and the plane wave transmission and reflection coefficients, as a function of incident power level for a variety of reentry flow field conditions. An implicit-explicit method is used to numerically integrate in time the coupled, nonlinear, parabolic partial differential equations. A very efficient algorithm is given for solving the coupled, tridiagonal system of equations for the electron and positive ion densities. For a typical set of reentry flow field conditions, graphs are presented of the electron density profile and the plane wave reflection and transmission coefficients for different incident power levels. The effects of varying the plasma transport coefficients are investigated in some detail. Also, the effects of varying the length of a high power pulse are investigated. (Author).

This book was released on 1973 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The computer program for calculating the high power microwave transmission coefficients of a chemically seeded reentry plasma has been described in two previous reports by the author. It has been explained how the computer code can optimize the amount of high power that can be transmitted from a reentry vehicle. The injection of electrophilic compounds into the reentry flow field can suppress the onset of antenna voltage breakdown, so that the transmitted power can be greatly increased. Using a half implicit-half explicit time integration scheme, the electron and ion transport equations coupled with Maxwell's equations are numerically integrated to determine the nonlinear reflection and transmission coefficients of a reentry plasma. Corresponding to the flow field conditions of a blunt nosed reentry vehicle (Trailblazer 2), graphs are presented to the electron density profile and plane wave reflection and transmission coefficients.

This book was released on 2013-03-09 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: TO THE SECOND EDITION In the nine years since this book was first written, rapid progress has been made scientifically in nuclear fusion, space physics, and nonlinear plasma theory. At the same time, the energy shortage on the one hand and the exploration of Jupiter and Saturn on the other have increased the national awareness of the important applications of plasma physics to energy production and to the understanding of our space environment. In magnetic confinement fusion, this period has seen the attainment 13 of a Lawson number nTE of 2 x 10 cm -3 sec in the Alcator tokamaks at MIT; neutral-beam heating of the PL T tokamak at Princeton to KTi = 6. 5 keV; increase of average ß to 3%-5% in tokamaks at Oak Ridge and General Atomic; and the stabilization of mirror-confined plasmas at Livermore, together with injection of ion current to near field-reversal conditions in the 2XIIß device. Invention of the tandem mirror has given magnetic confinement a new and exciting dimension. New ideas have emerged, such as the compact torus, surface-field devices, and the EßT mirror-torus hybrid, and some old ideas, such as the stellarator and the reversed-field pinch, have been revived. Radiofrequency heat ing has become a new star with its promise of dc current drive. Perhaps most importantly, great progress has been made in the understanding of the MHD behavior of toroidal plasmas: tearing modes, magnetic Vll Vlll islands, and disruptions.
