ELECTROMAGNETIC PROPERTIES OF PLASMAS
Abstract
This report describes a recommended program of laboratory study of environmental conditions around hypersonic missiles. The study of the properties of plasmas has been carried on to date using noble gases and will be extended to oxygen nitrogen mixtures. Three diagnostic techniques capable of being used simultaneously are: (1) measurements made by propagating 10 kmc across the plasmas behind the shockwave, (2) measure ments made of the radiated power at 10 kmc emitted by the hot gas, and (3) measurements made of the Stark broadening of certain spectral lines. These methods will yield information on the degree and rates of ionization, electron density, electron temperature, collision cross section, attenuation and phase velocity constants, and reflection coefficient. This information will provide an understanding of mechanism of attenuation of radio signals through the plasma and will lead to approaches for solution of this problem.
