چکیده

The evolution of shell modulations near peak compression of direct-drive spherical-target implosions has been measured using the 60-beam, 30-kJ UV OMEGA laser system. The spatial size and amplitude of shell-areal-density modulations decrease during the target compression, then increase during its decompression as expected. The shell uniformity at peak compression has been increased by reducing single-beam, laser-drive nonuniformity.

Analyzing the Structure of Shell Modulations Around Peak Compression of Spherical Implosions

Programs were created to analyze the structure of shell modulations at peak compression of spherical implosions. Measurements of the modulations were taken by using absorption of titanium-doped layers placed at distances 1,5,7, and 9 pm from the inner surface of 20 pm-thick plastic CH shells filled with 18 atm of D ~ H ~ gas. These nonuniformities were measured using ratios of monochromatic tar...

124 LLE Review, Volume 83 Introduction In inertial confinement fusion (ICF), spherical targets are driven either directly with laser beams1 or indirectly with x-ray drive.2 Initial target nonuniformities, either existing or created by the drive, can grow because of hydrodynamic instabilities disrupting the implosion and reducing its thermonuclear yield.3 Therefore, it is important to measure th...

At this time, the hot core and the inner surface of th...

242 LLE Review, Volume 76 In an inertial confinement fusion (ICF) implosion, the target is hydrodynamically unstable, and, as a result, mass modulations in the target (either existing or created) can grow to be large enough to disrupt the implosion, thereby reducing its thermonuclear yield.1 In direct-drive ICF, the nonuniformities in the drive laser can create mass modulations in the target by...
