| Interaction of deuterium and tritium overdense bunches accelerated to relativistic velocities by ultra high intensity laser pulses is considered. Profiles and durations of ultrashort pulses as well as the thicknesses and densities of thin plasma foils for obtaining bunches with optimum relative velocities and highest possible concentrations for fusion were selected. Reaction density ((10)^25 (cm)^(-3)) and number of generated high energetic neutrons was calculated ((10)^13) and found equal to 109 neutrons per Joule. In addition, the processes of closely staked deuterium-tritium and deuterium-helium3 targets acceleration and compression were investigated. The results of the study show that ultra high intensity laser pulses can be used in laser fusion for ignition of the target core to reach high gain. |
