The mechanisms associated with the interaction of a realtivistic proton beam with a target material are summarized, and a simple analytic calculation for each mechanism relates its importance in the deposition of energy. Because it was found that possible significant contributions could be related to collective effects, the first three moments of the Boltzmann-Vlasov equation and the equations necessary to describe the internal and external electromagnetic fields associated with the target are developed. These equations are then formulated into a computer program to describe the collective interaction process. Sample runs demonstrate the ability of the computer model to predict plasma oscillation at the proper frequency. Although an instability developed in the runs with the beam approaching the target, the preliminary analysis was accomplished, and the need for future detailed analysis of this process was established.
