Analysis of the dispersion of a charged ion beam indicates that the limitations imposed by the space charge are quite severe. Beam dispersion due to random thermal velocity distribution is not as severe as that of space charge dispersion. Use of the beam for communications will be of the order of a few thousand miles at most. The effects of Rayleigh, Thompson, and Compton scattering of light by beam particles in the presence of the radiation field of the sun are negligible. The analysis of solar winds and particle clouds in space indicates that the beam particle mean free path is quite large so that there is no significant limitation imposed by their presence. The problem of neutral beam generation is discussed. The possibility of employing the pinch effect upon a beam in the presence of the atmosphere is not feasible. Use of the radiation produced by impact ionization of the atmosphere by means of a beam is impractical on the basis of beam power requirements. Propulsion offers the best possibility for the application of the beam. Deviation and dispersion of the beam in electrostatic and magnetic fields in space are analyzed. The limitations imposed by these effects are not as great as those already found. The geometrical problems of aiming a beam to strike a target in the fields in space are considered.
