Abstract

In Part I, results of penetration depth calculations applied to single pellets under thermonuclear plasma conditions are described. Calculations were performed for different pellet size and velocity combinations. Data corresponding to the neutral gas shielding ablation model and a magnetic shielding approximation are compared. Part II is concerned with the pellet sizes and pellet velocities required for central fuelling. If only neutral gas shielding takes place, central fuelling with realistic pellet velocities is not possible. The presence of magnetic shielding may reduce the velocity requirements to technically feasible values. The study of the ablation physics and the development of comprehensive ablation models thus appear to be of primary importance.
