RESEARCH DIRECTED TOWARD PLASMA STABILITY STUDIES IN MAGNETIC FIELDS.
Abstract
Section I describes preliminary x-ray studies of high density plasmas produced by exploding wires. Symptoms of turbulence, which are always observable in lightpicture studies, were not detected in the x-ray photographs. Further investigations are suggested wherein dual x-ray equipment might be used together with more accurate scanning techniques. Section II describes an interferometer with laser source as a means of determining electron densities. Further described therein is an electron beam instrument for determining heavy particle densities. Section III discusses the physical characteristics and implications of the moving radiation sources observed in the shock tube experiments. In Section IV, the electrical conductivity of a partially ionized gas in a uniform magnetic field is determined. This extension of the Sen-Wyller magneto-ionic theory was motivated by the fact that ionospheric, interstellar, and laboratory plasmas do contain neutral gas molecules. In Section V, a nonlinear analysis of plasma oscillations reveals the existence of: (1) composite modes resulting from the repeated mutual interaction of the incident field and plasma components; (2) an infinity squared of Larmor resonances. Section VI is a conjectural study of small amplitude wave motions in a two-stream hydromagnetic gas with Hall perturbations. (Author)
