THEORETICAL STUDY OF MAGNETOHYDRODYNAMIC WAVE PROPAGATION AND EXPERIMENTAL STUDY OF COLLISIONAL EFFECTS ON WAVE PROPAGATION.
Abstract
Two problems relevant to the magnetotelluric detection of high altitude nuclear detonations are treated in this final report: (1) Theoretical and numerical computations of the propagation of magnetohydrodynamic waves generated by a current source in a realistic ionosphere including dipole magnetic field and spherical earth. The relationship of the theory to magnetic signals observed from the Star Fish nuclear detonation is discussed. (2) The effect of collisions on the propagation of ion-acoustic waves in the ionosphere is considered. The qualitative behavior is deduced after a review of current knowledge of the subject. A laboratory experiment to check these conclusions and obtain quantitative data is described. (Author)
