Issues in capsule fabrication and injection into a wet-walled IFE reactor

Feasibility for mass production of high gain targets for a laser fusion reactor is discussed focusing on the capsule fabrication and the life of cryogenic targets heated with the latent heats of residual gas in the reactor. The model targets are (a) a solid DT layer in a relatively thick polystyrene capsule and (b) solid DT in a cryogenic DT foam ablator with a thin gas barrier. The latter target involved various issues concerning its fabrication process and both targets cannot survive in a conceptual laser fusion reactor KOYO.
