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...

90 LLE Review, Volume 82 Introduction To achieve ignition and gain in inertial confinement fusion (ICF), a spherical target must be compressed with a highly uniform drive mechanism.1–3 Perturbations in the drive can lead to a distorted fuel core as well as hydrodynamic instabilities, which cause the colder ablator material to mix with the fuel in the central hot spot, effectively quenching the ...
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 کاملPerformance of Direct-Drive Cryogenic Targets on OMEGA
LLE Review, Volume 113 16 Introduction In the inertial confinement fusion (ICF) approach to fusion, a spherical shell filled with a deuterium–tritium (DT) mixture is compressed to reach a temperature of 10 to 12 keV in the lower-density central core region (hot spot) to initiate a burn wave through the higher-density colder main fuel surrounding the core.1–3 The main fuel areal density (tR) at ...
