Heavy ion fusion simulation in key parameters optimization using multilayer fuel target and the effectiveness of ponderomotive force in ion acceleration

In heavy ion fusion through Inertial Confinement Fusion, key points such as the production and driver energy delivery, fuel pellet design, physics of fuel pellet implosion, nuclear fusion reactor design, etc. are important. In this paper, we determine the stopping power, deposited energy, and the produced flux of secondary particles using the irradiation of multilayer spherical fuel pellet containing DT, D³He, and p¹¹B by Pb and Cs heavy ion beams with energies of 8 and 10 GeV via GEANT4 simulation code, respectively. This work shows that by changing the selected heavy ion beam and its energy, as well as by changing the thickness of the layers and the type of ingredients in the fuel pellet, the obtained results change. The optimum gain of the deposited energy due to the choice of two selective heavy ion beams Pb and Cs that we obtained in this study, is related to the DT target compared to the two aneutronic targets of D³He and P¹¹B in both energy 8 and 10 GeV. Finally, we use laser-plasma accelerator and determine theoretically the ponderomotive force.
