Alternative approaches to the design of targets for a hybrid thermonuclear station

Targets with low degrees of compression, such as those with internal energy deposition, two-stage conical targets for lasers emitting pulses of duration of the order of 100 ns, and multilayer shell targets for short-pulse long-wavelength CO{sub 2} and CO lasers may prove acceptable for hybrid thermonuclear reactors with high values (of the order of 10{sup 3}) of the gain in the blanket. Estimates and one-dimensional calculations of the compression of such targets are reported for the laser radiation energy range 0.2-2 MJ. (interaction of laser radiation with matter. laser plasma)
