Abstract

In this research, having applied the modeling of D/³He fuel burning, the isentropic parameter and entropy are studied. It is shown that the Fermi degeneracy plays an important role in reducing the pressure, energy driver and the fractional burn-up. Based on recent progresses in the laser particle accelerators’ research, we have examined the ignition of a D/³He fuel to achieve the gains of order 58. The obtained results show that the energy required to compress a D/³He fuel with a density of 3.9 × 10⁴ g/cm³, is 3.3 × 10⁷ J/g. With the confinement parameter, 80 g/cm² and a two times reduction of the isentropic parameter, the increased rate of the target gain is 31%.
