Lithium Deuteride/Lithium Tritide Pellet Injection

Injection of lithium deuteride or lithium tritide pellets into fusion devices could simultaneously provide partial deep-penetration fueling of the core plasma and replenishing of the lithium wall/divertor coating. The main problems are possible impurity accumulation and undesirable effects of lithium films on windows, mirrors, and insulators. The potential benefits include better pellet manufacture, acceleration, transmission, penetration, and good lithium wall/divertor coating.
