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
