It is shown that there is a principal possibility of effective burning with gain G > 200 of ecologically clean DHe3 fuel in reactor-type targets without increase of driver energy. The proper target consists of DHe3 fuel and a D-T ignitor with a central hot spark. Under proper conditions, the D-T burning wave reaches the DHe3 range with the temperature sufficient for ignition of DHe3 plasma. The simulation was carried out by means of TERA code based upon self-consistent solution of a kinetic equations system for products of primary and secondary thermonuclear reactions by the Monte Carlo method and a hydrodynamic equations system.

Results of the analysis and numerical calculations of continuous spectra of multicomponent multicharged plasma radiation are presented. Possibilities of control of the radiation spectrum by the mixture composition variation and programming in time the pulsed discharge current of the supply source are considered. Free and forced (by energy deposition or additional cooling) relaxation time estimations permit the definition of discharge parameters when plasma formation goes on under nonequilibrium conditions, leading to controlled energy redistribution over the spectrum.
