Abstract
The performance of triple-picket deuterium-tritium cryogenic target designs on the OMEGA Laser System [T.R. Boehly et al., Opt. Commun. 133, 495 (1997)] is reported. These designs facilitate control of shock heating in low-adiabat inertial confinement fusion targets. Areal densities up to 300 mg=cm[superscript 2] (the highest ever measured in cryogenic deuterium-tritium implosions) are inferred in the experiments with an implosion velocity ~3×10[superscript 7] cm=s driven at peak laser intensities of 8×10[superscript 14] W=cm[superscript 2]. Extension of these designs to ignition on the National Ignition Facility [J. A. Paisner et al., Laser FocusWorld 30, 75 (1994)] is presented.
