INVESTIGATION OF THE INTERACTION OF A PREIONIZED GAS WITH AN ELECTRIC ARC.
Abstract
The free-burning D.C. electric arc and plasma jet operating in argon at atmospheric pressure were accurately calibrated and compared with independent measurements made in other laboratories. These plasmas which constitute the basic components of a Lorentz force plasma accelerator were interacted to provide a general concept of the distorted plasma geometry to be encountered in a future basic research program aimed at the investigation of interacting plasmas in an external magnetic field. Because of the lack of circular symmetry in the interacting system of plasmas, new analytical methods were developed for converting externally measured integrated spectral line intensities to emission coefficients, a required step in the process of determining plasma temperatures. Theoretical consideration was also given to the effect of nonequilibrium on measured spectral line emission coefficients and the possibility of experimentally detecting any existing difference between electron and heavy particle temperatures. The effect of this nonequilibrium on gas density and static enthalpy was included. (Author)
