This book was released on 2010 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-frequency fluctuations of plasma density, floating potential, ion saturation current, visible light intensity, and edge magnetic field are routinely observed in the Levitated Dipole Experiment (LDX). For the purposes of this thesis, we define low-frequency as W “Wbe where Wbe is the electron bounce frequency. These fluctuations in a laboratory dipole confined plasma lead to turbulence mixing that maintain peaked density profiles. The relationship between the different types of low-frequency fluctuations and plasma density transport is considered. Two 16-channel photodiode arrays were designed and constructed to study the spatial and temporal structure of these fluctuations as part of this dissertation. In addition to the photodiode arrays, a four-channel microwave interferometer is used to estimate the density profile and to measure density fluctuations in the plasma. Several electrostatic probes, including a 24-channel floating probe array, measure fluctuations at the plasma edge and eight Mirnov coils measure magnetic fluctuations. The fluctuations fall into three general categories: broadband, turbulent fluctuations observed during nearly all plasma conditions; quasi-coherent fluctuations with low azimuthal mode numbers and peak frequencies on the order 1 kHz observed during discharges with low neutral pressure; and coherent fluctuations with zero toroidal mode number and peak frequencies on the order of 100 Hz, observed during discharges with moderate neutral fueling. The relationship between time-averaged fluctuation characteristics and plasma parameters are explored. The spatial structure of the fluctuations for several representative shots are discussed. The turbulent fluctuations and concurrent density profiles are compared to quasilinear diffusion of interchange mixing in dipolar plasmas for cases where the fluctuations are random. I show that the quasilinear diffusion equation agrees well with the experimental observations of random fluctuations, supporting the conclusion that interchange mixing is causing inward transport that results in peaked density profiles. For other cases, where nonlinear effects appear to dominate the plasma dynamics, the saturated fluctuation amplitudes are compared to the plasma density profiles.

Available in PDF, EPUB and Kindle. Book excerpt: Random fluctuations of the electron density of a plasma medium degrade the characteristics of a microwave signal which is passed through it. Typically the examination on a spectrum analyzer of an rf signal which has been passed through a la oratory plasma reveals a transfer of energy into sidebands of the original frequency. In dc discharges the main components observed are those due to the strong oscillations which occur in the low-frequ ncy range elow one megacycle. A theory of phase modulation of an rf signal by the low-frequency fluctuations of a plasma is described. It is shown that strong sidebands should be expected, and that under certain circumstances the original carrier amplitude may become zero. The res lts obtained agree well with experimental measurements carried out on a plasma column modulated in density by an external lowfrequency signal. (Author).

Download or read book Introduction to Space Physics written by Margaret G. Kivelson and published by Cambridge University Press. This book was released on 1995-04-28 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: All aspects of space plasmas in the Solar System are introduced and explored in this text for senior undergraduate and graduate students. Introduction to Space Physics provides a broad, yet selective, treatment of the complex interactions of the ionized gases of the solar terrestrial environment. The book includes extensive discussion of the Sun and solar wind, the magnetized and unmagnetized planets, and the fundamental processes of space plasmas including shocks, plasma waves, ULF waves, wave particle interactions, and auroral processes. The text devotes particular attention to space plasma observations and integrates these with phenomenological and theoretical interpretations. Highly coordinated chapters, written by experts in their fields, combine to provide a comprehensive introduction to space physics. Based on an advanced undergraduate and graduate course presented in the Department of Earth and Space Sciences at the University of California, Los Angeles, the text will be valuable to both students and professionals in the field.
