Diagnosing 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 ...
متن کاملA compact neutron spectrometer for characterizing inertial confinement fusion implosions at OMEGA and the NIF.
A compact spectrometer for measurements of the primary deuterium-tritium neutron spectrum has been designed and implemented on the OMEGA laser facility [T. Boehly et al., Opt. Commun. 133, 495 (1997)]. This instrument uses the recoil spectrometry technique, where neutrons produced in an implosion elastically scatter protons in a plastic foil, which are subsequently detected by a proton spectrom...
متن کاملEvidence for stratification of deuterium-tritium fuel in inertial confinement fusion implosions.
Measurements of the D(d,p)T (dd) and T(t,2n)(4)He (tt) reaction yields have been compared with those of the D(t,n)(4)He (dt) reaction yield, using deuterium-tritium gas-filled inertial confinement fusion capsule implosions. In these experiments, carried out on the OMEGA laser, absolute spectral measurements of dd protons and tt neutrons were obtained. From these measurements, it was concluded t...
