Laser-Induced Adiabat Shaping by Relaxation in Inertial Fusion Implosions
Technical Report
·
OSTI ID:808740
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 the maximum on the outer ablation surface to lower Rayleigh-Taylor growth rates, and the minimum on the shell inner surface for high compressibility and high neutron yields. Laser-induced adiabat shaping is produced via relaxation using a weak pre-pulse followed by laser shut-off and the main laser pulse.
