“…Even now plasma states with peak pressures of hundreds±thousands of megabars, temperatures of up to 10 9 K, and energy densities of 10 9 J cm À3 , the latter being comparable to the energy density of the nuclear substance, have come to be subjects of laboratory investigations [3,4,22,29,64,65]. According to the notions elaborated to date [23 ± 25, 28], to implement a controlled thermonuclear reaction with inertial plasma confinement requires delivering an energy of several megajoules to a spherical target in 10 À9 s to produce at its center a deuterium±tritium plasma with extremely high parameters: T % 1À2 Â 10 8 K, r % 200 g cm À3 , p % 150 ± 200 Gbar, which are close to the conditions at the solar center.…”
