First Results from Cryogenic Target Implosions on OMEGA
LLE Review, Volume 90 49 Introduction The base-line direct-drive ignition target design for the National Ignition Facility (NIF)1 is a thick cryogenic DT-ice layer enclosed in a thin CH shell.2,3 In direct-drive inertial confinement fusion (ICF)4 a spherical target is illuminated by a large number of laser beams to provide a spherically symmetric implosion. Target implosions with cryogenic DT f...

82 LLE Review, Volume 78 Direct-drive inertial confinement laser fusion is accomplished by uniformly illuminating spherical fuel-bearing targets with high-power laser beams, ablatively driving implosions that result in large increases in density and temperature. Current large laser systems such as the University of Rochester’s OMEGA laser, which is capable of both directand indirectdrive implos...

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 کاملThe saturn target for polar direct drive on the national ignition facility.
A new target design concept is proposed for direct-drive implosions while the National Ignition Facility is in its initial, indirect-drive configuration. It differs from earlier "polar-direct-drive" designs by adding a low-Z ring around the capsule equator. Refraction in the plasma formed around this ring permits time-dependent tuning of the capsule drive uniformity. An optimized simulation sho...
