ALTERNATIVE APPROACHES TO THE DESIGN OF TARGETS FOR A HYBRID THERMONUCLEAR STATION

Targets with low degrees of compression, such as those with internal e nergy 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 CO2 and CO lasers may prove acceptable for hybrid thermonuclear reactors with high values (of the order of 10(3) ) of the gain in the blanket. Estimates and one-dimensional calculatio ns of the compression of such targets are reported for the laser radia tion energy range 0.2-2 MJ.
