Laser-Induced Adiabat Shaping by Relaxation in Inertial Fusion Implosions
TOAK-B135 The theory of laser-induced adiabat shaping is carried out for inertial confinement fusion (ICF) capsules. It is shown that a significant improvement of the stability characteristics of ICF implosions can be achieved by shaping the adiabat inside the imploding shell. The optimized adiabat profile has a maximum on the outer ablation surface to lower Rayleigh-Taylor growth rates, and a minimum on the shell inner surface for high compressibility and high neutron yields. Laser-induced adiabat shaping is produced via relaxation using a weak prepulse followed by laser shut-off and the main laser pulse.
