Self-Similar Structure and Experimental Signatures of Suprathermal Ion Distribution in Inertial Confinement Fusion Implosions.
The distribution function of suprathermal ions is found to be self-similar under conditions relevant to inertial confinement fusion hot spots. By utilizing this feature, interference between the hydrodynamic instabilities and kinetic effects is for the first time assessed quantitatively to find that the instabilities substantially aggravate the fusion reactivity reduction. The ion tail depletio...
متن کاملDiagnosing indirect-drive inertial-confinement-fusion implosions with charged particles
High-energy charged particles are being used to diagnose x-ray-driven implosions in inertial-confinement fusion. Recent measurements with vacuum hohlraums have resulted in quantitative characterization of important aspects of x-ray drive and capsule implosions. Comprehensive data obtained from spectrally resolved, fusion-product self-emission and time-gated proton radiographs with unprecedented...
متن کاملSymmetric inertial confinement fusion implosions at ultra-high laser energies.
Indirect-drive hohlraum experiments at the National Ignition Facility have demonstrated symmetric capsule implosions at unprecedented laser drive energies of 0.7 megajoule. One hundred and ninety-two simultaneously fired laser beams heat ignition-emulate hohlraums to radiation temperatures of 3.3 million kelvin, compressing 1.8-millimeter-diameter capsules by the soft x-rays produced by the hoh...
متن کاملAdiabat Shaping in Direct-Drive Inertial Confinement Fusion Implosions
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 ...
