A THEORETICAL AND EXPERIMENTAL INVESTIGATION OF ION ACOUSTIC WAVE DISPERSION IN A NON-UNIFORM HIGHLY IONIZED ARGON PLASMA.
Abstract
Ion acoustic waves have been artificially excited and detected in the Steady State Plasma Facility at the Naval Post-graduate School by a magnetic excitation device and an optical detection system. The dispersion of these waves has been studied as a function of the exciting frequency and the confining static magnetic field. Dispersion curves are presented which compare the experimental data to a new dispersion equation which is derived in the present thesis. After the validity of this dispersion relation is demonstrated, the measurements are used as a diagnostic tool, and five operating parameters of the plasma facility are deduced from the measurements. Theories are presented to explain the behavior of the dispersion curves and three of the five operating parameters. (Author)
