Investigations on Plasma Instabilities.
Abstract
The report summarizes the plasma research work during 1970 of the Institute for Theoretical Physics, Innsbruck University. The scientific part contains, among other things, the following items: Current research items and progress achieved within the frame of the U.S. project on plasma instabilities. The work on the stability behavior of hydromagnetic Poiseuille flows has been concluded. The new program aiming at a more satisfactory understanding of non-linear plasma phenomena has been initiated by extending the general and powerful concept of local thermodynamic potential to the stability analysis of MHD plasmas, and by re-examining the concepts of frequency and wave number as related to non-linear waves. The work on high-frequency oscillations in arbitrary plasma configurations has proceeded to the final stage of numerical evaluation of the general dispersion relation. Investigations into the field of Vlasov turbulence suggest that there might exist a close connection between the bunching phenomenon, trapped-particle modes, and turbulent heating. A comprehensive literature survey on plasma instabilities is being written. Courtesy report on the Austrian project. This project includes theoretical and experimental work on Q-machines, the numerical treatment of realistic MGD channel flow configurations, as well as the search for new solutions to the basic equations by means of similarity transformations.
