THEORETICAL STUDY OF MAGNETOHYDRODYNAMIC WAVE PROPAGATION AND EXPERIMENTAL STUDY OF COLLISIONAL EFFECTS ON WAVE PROPAGATION.

Abstract

Some aspects of the magnetic signal observed following a high altitude nuclear detonation appear to be due to magnetohydrodynamic wave propagation on a global scale. Solutions to the poloidal (magnetoacoustic) wave equation for simple models of the ionosphere both with and without a source present are discussed in relation to these observations. Collisions between charged and neutral particles can affect the propagation of magnetohydrodynamic waves in the lower ionosphere. The phenomena can be studied experimentally by propagating ion-acoustic waves in a laboratory plasma. The requirements for experimental scaling are discussed in detail and an experimental setup is described. (Author)
