The feasibility of pellet re-fuelling of a fusion reactor
Abstract
The required refueling rate, reasonable pellet size, and dominant energy fluxes affecting an ablation process are discussed. Current shielding models of pellet ablation are reviewed, along with the problems concerning pellet deceleration, its injection speed, and deposition of ablated materials. The interaction of a pellet with its surrounding plasma and the effect on the ignition requirement and particle confinement time are outlined. A pellet source is described, and experiments are covered.
