Computational Investigation of Realization of Unshocked Compression and Thermonuclear Burn in Nonspherical Target of Heavy-Ion Driven Fusion.

Abstract:

Below a stated approach about realization of unshocked compression in heavy-ion driven fusion with the help of profiled deposit of ion energy in regions absorb and tamper presents itself prospect. Under peak specific power 9000(TW/g) and amount of ion energy ~0.4MJ were obtained <ρr>_{DT} = 0.30g/cm^{2} and G ~12.5 for М_{DT} = 0.105mg. In two-dimensional case, under assumption Q(t,θ)=Q(t)·ψ(θ) and compensation of asymmetry by modification thickness of pusher was found profiled deposit of ion energy. By parameter optimization of profiled deposit of ion energy, if amount ion energy is ~1.2MJ, energy gain and degree of compression are close to corresponding one-dimensional result, i.e. practically preserves spherical cumulating.
