Abstract : The following report describes our present understanding and recent results from an analysis of the effects of elastic scattering on neutral beam penetration. The important factors affecting neutral beam propagation in the upper atmosphere at altitudes of 200-250 km are discussed. Two primary factors affecting the beam quality are the accuracy of beam collimation and the effect of collisions between the beam particles and the background atmospheric particles. A further factor is ionization of the beam particles in terms of radiation or waves and instabilities that may result from the collective interaction between the ionized beam particles and the charged particles in the background atmosphere.
