This book was released on 2005 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under this contract, Northwest Research Associates (NWRA) is performing measurements of the ionosphere in order to investigate plasma phenomena in both the natural ionosphere and in the ionosphere perturbed by the High-frequency Active Auroral Research Program (HAARP) high-frequency heater. The research being conducted falls within Hanscom Technical Areas 3(a), "Ionospheric Effects Research and Department of Defense Systems," and 3(b), "Ionospheric Research Technology," of the Broad Agency Announcement VS-O3-Ol released by the Air Force Research Laboratory (AFRL). As a contribution to Technical Area 3(b), we are collaborating with scientists and engineers from AFRL, the Naval Research Laboratory (NRL), and other research organizations in the application of diagnostic instrumentation to HAARP. Among the HAARP instruments that we are applying to ionospheric research are three NWRA ITS1OS coherent radio receiving systems for measuring relative Total Electron Content (TEC) and recording scintillation, and an Ashtech Model Z-FX UPS receiver for measuring absolute TEC. We are posting TEC from these instruments, and phase-scintillation records from the ITS10S receivers, on the HAARP Web site (www.haarp.alaska.edu) for telescience applications and for decision-making during active experiments, and we are also focusing on inverting the TEC data tomographically to produce images of the F layer over Alaska. Research topics under the foregoing objectives are reported in Section 2.
Download or read book Plasma Heating Through Parametrically Induced Turbulence written by Arthur Lawrence Pavel and published by . This book was released on 1976 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electromagnetic waves have been shown to be capable of significantly modifying both the magnetospheric and ionospheric plasma. Laboratory studies of the plasma instabilities generated in microwave-plasma interactions have helped to understand the geophysical experiments. Microwave-plasma research has also been useful in modeling the interaction of lasers and plasmas, particularly in relation to efforts using pulsed lasers to compress and heat plasma to thermonuclear conditions. An experiment is described which investigates the evolution of the parametric instability which occurs with near resonant matching of the microwave frequency and plasma frequency. Near threshold, a finely detailed spectrum of satelite electron plasma waves is observed. These waves break down into a turbulent plasma condition with a marked change in power absorbed by the plasma. The plasma passes through several distinctive regimes of turbulent plasma conditions. At the highest power levels used, there are plasma waves hundreds of megacycles from the driving frequency. The plasma is found to absorb a significant amount of power and heat electrons to high energies. (Author).
Download or read book Transport Phenomena in Partially Ionized Plasma written by Vladimir. A. Rozhansky and published by Gordon & Breach Science Publishers. This book was released on 2001-09 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transport phenomena in plasmas are the relatively slow process of particle, momentum and energy transport in systems in a state of mechanical equilibrium. In contrast to neutral gases, these phenomena in plasmas are greatly influenced by self-consistent fields in particular electric fields. These can produce particle and energy fluxes, in addition to those generated by the homogeneity of the plasma composition and temperature. As a result, the physical effects accompanying transport phenomena in plasmas are far more numerous and complicated than those in neutral gases, and the solution of corresponding problems is more difficult. The effects however, are usually far more interesting and sometimes surprising.Presenting a systematic survey and analysis of the main mechanism of transport phenomena in plasma this book also gives examples of gradually increasing complexity to illustrate these mechanisms and the relationships between them. Special attention is paid to the analysis of experimentalmeasurements, and the relevant processes are considered analytically as well as qualitatively.Many of the problems dealt with are of considerable practical interest, and the phenomena described often determine the main characteristics of processes and devices. Therefore this book will be of interest to researchers who need to know the properties of real, specific systems, as well as to engineers and advanced students in the physics of plasmas, semiconductors, various types of gas discharges and the ionosphere.
Download or read book The WIND HAARP Experiment Initial Results of High Power Radiowave Interactions with Space Plasmas written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results from the first science experiment with the new HF Active Auroral Research Program (HAARP) facility in Alaska are reported. The initial experiments involved transmission of high frequency waves from HAARP to the NASA/WIND satellite. The objective was to investigate the effects of space plasmas on high power (approx. 300 kW) radiowave transmission from the ground to high altitudes in the magnetosphere. The data acquired suggest that structured space plasmas along the propagation path impose a power law spectrum of intensity fluctuations on the transmitted waves, resembling that of scintillation interactions. However, because the transmitted wave frequencies are near ionospheric plasma frequencies, other types of wave-plasma interactions may occur. The measurements can provide an important new diagnostic tool for space plasmas.
Download or read book Plasma Instabilities in the Equatorial F region written by Edward P. Szuszczewicz and published by . This book was released on 1979 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accumulating information regarding the equatorial F-region ionosphere has proven it to be a particularly important domain for the communications and ionospheric sciences as well as investigation of fundamental plasma processes that have counterparts in atmospheric releases and controlled laboratory experiments. This wide range of interest has in recent years brought considerable intensity into equatorial investigations with major technical, scientific, and engineering advances contributing to our current understanding and future plans for adaptive communication system design and ionospheric modification and control. Rapid advances require occasional synthesis in order to draw proper perspectives and establish an improved definition of near-term and longer range plans. This document bears that objective, particularly as it relates to radar, rocket, and satellite studies of the turbulent ionospheric plasma state, the theoretical and computational descriptions, and chemical releases for controlled ionospheric modifications. Emphasis is placed on important relationships involving spread F, naturally-occurring ionospheric bite-outs, and artificial ionospheric holes. Current understanding is reviewed, deficiencies identified, and future programs involving the Naval Research Laboratory are discussed.

Download or read book Nonlinear Phenomena in the Ionosphere written by A. Gurevich and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear effects in the ionosphere (cross modulation of radio waves) have been known since the 1930s. Only recently, however, has the rapid increase in the power and directivity of the radio transmitters made it possible to alter the properties of the ionosphere strongly and to modify it artificially by applying radio waves. This has revealed a variety of new physical phenomena. Their study is not only of scien tific interest but also undisputedly of practical interest, and is presently progressing very rapidly. This monograph is devoted to an exposition of the present status of theoretical research on this problem. Particular attention is paid, naturally, to problems in the development of which the author himself took part. It is my pleasant duty to thank V. L. Ginzburg, L. P. Pitaevskii, V. V. Vas'kov, E. E. Tsedilina, A. B. Shvartsburg, and Va. S. Dimant for useful discussions and for valuable remarks during various stages of the work on the problem considered in this book. Contents 1.
