First observations of nonhydrodynamic mix at the fuel-shell interface in shock-driven inertial confinement implosions.

چکیده
A strong nonhydrodynamic mechanism generating atomic fuel-shell mix has been observed in strongly shocked inertial confinement fusion implosions of thin deuterated-plastic shells filled with 3He gas. These implosions were found to produce D3He-proton shock yields comparable to implosions of identical shells filled with a hydroequivalent 50∶50 D3He gas mixture. Standard hydrodynamic mixing cannot explain this observation, as hydrodynamic modeling including mix predicts a yield an order of magnitude lower than was observed. Instead, these results can be attributed to ion diffusive mix at the fuel-shell interface.

Shock Convergence and Mix Dynamics in Inertial Confinement Fusion
Understanding the phenomena of shock propagation and of turbulent mix induced by Rayleigh-Taylor (RT) instability growth is of critical importance for ignition and high gain in inertial confinement fusion (ICF). Capsule assembly and hot-spot formation require careful timing of multiple shocks to maximize hot-spot heating while minimizing heating of the main fuel. Unmitigated mixing of the main ...

Relations between stagnation and in-flight phases are derived both analytically and numerically, for hydrodynamic variables relevant to direct-drive inertial confinement fusion implosions. Scaling laws are derived for the stagnation values of the shell density and areal density; also the hot spot pressure, temperature and areal density. Simple formulas are derived for the thermonuclear energy g...

Adiabat shaping in inertial confinement fusion (ICF) capsules has been proposed as a method for increasing the stability of ICF implosions without compromising capsule compressibility and one-dimensional yield. The optimal adiabat profile has a maximum on the outer, ablation surface for higher ablative mitigation of the Rayleigh–Taylor (RT) instability, and a minimum on the shell inner surface ...
