Series of numerical calculations in two-dimensional and multi-temperature approximations was carried out to study the problems of deuterium thermonuclear targets burning. The use of DT pill for igniting deuterium target offers conditions for thermonuclear burning. Cylindrical deuterium targets and heavy-ion beams with charge compensation are studied within Fast Ignition scheme. Special compressing ion beams with the energy Ec ≥ 1 000 MJ are used for obtaining the fuel density ρ ~ 30 ÷ 100 g/cm3 and the compression parameters ρR ~ 4 g/cm2. The igniting beams with high power density Jm ~ 4 ⋅ 106 TW/g and the energy Eign ~ 24 MJ are used to gain a wave of thermonuclear burning in a compressed cylindrical channel. For igniting fuel the masses of DT pills are considered at the level m ~ 100 mg. The propagation of thermonuclear burning wave along the target and thermonuclear energy-release Ef ≥ 10 000 MJ have been arrived at in calculations of targets with beryllium shell.
