Direct-Drive, Cryogenic Target Implosions on OMEGA
78 LLE Review, Volume 102 Introduction Thermonuclear ignition via direct-drive, laser-driven, inertial confinement fusion1 (ICF) will be accomplished by the nearuniform illumination of spherical cryogenic deuterium– tritium (DT) fuel-bearing capsules with high-power laser beams. Achieving thermonuclear ignition and gain will require symmetric compression of the DT-fuel hot spot to high areal de...
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 کاملStudy of Direct-Drive, DT-Gas-Filled-Plastic-Capsule Implosions Using Nuclear Diagnostics on OMEGA
54 LLE Review, Volume 86 Introduction High-gain inertial confinement fusion (ICF) requires uniform compression of a spherical capsule to a state of high density and temperature;1–3 current research is aimed at finding ways to achieve this goal. This article describes how a range of traditional and new nuclear diagnostics are used to study the compression performance of deuterium-tritium (DT)-fi...
متن کاملHigh-areal-density fuel assembly in direct-drive cryogenic implosions.
The first observation of ignition-relevant areal-density deuterium from implosions of capsules with cryogenic fuel layers at ignition-relevant adiabats is reported. The experiments were performed on the 60-beam, 30-kJUV OMEGA Laser System [T. R. Boehly, Opt. Commun. 133, 495 (1997)10.1016/S0030-4018(96)00325-2]. Neutron-averaged areal densities of 202+/-7 mg/cm2 and 182+/-7 mg/cm2 (correspondin...
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 ...
