Symmetric 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 کاملStudy of direct-drive capsule implosions in inertial confinement fusion with proton radiography
Implosions of spherical and cone-in-shell targets in direct-drive inertial confinement fusion (ICF) are studied with proton radiography. Time-gated, 15-MeV proton images provide a unique and comprehensive picture of ICF implosions that cover all the implosion phases from acceleration, through coasting, deceleration, to stagnation. Observation and study have resulted in the discovery and charact...
متن کاملThin shell, high velocity inertial confinement fusion implosions on the national ignition facility.
Experiments have recently been conducted at the National Ignition Facility utilizing inertial confinement fusion capsule ablators that are 175 and 165 μm in thickness, 10% and 15% thinner, respectively, than the nominal thickness capsule used throughout the high foot and most of the National Ignition Campaign. These three-shock, high-adiabat, high-foot implosions have demonstrated good perform...
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 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 ...
