Abstract

The re-emitted images of the frame camera indicated that the high-Z (Bi) capsule deviated about 29 μm from the center of the hohlraum in experiments at the Shenguang-II (SG-II) laser facility; however, investigations on this issue have seldom been performed. The influence of three dimensional o?sets of a capsule on its radiation asymmetry in inertial confinement fusion (ICF) will be analyzed in this paper. Simulations demonstrate that the axial o?set of 100 μm of a capsule from the center of the hohlraum brings an additional 3.5% radiation drive asymmetry and 6.5% P1 asymmetry (Legendre odd model) on the capsule in the SG-II laser facility, and the o?set must be within 25 μm if the P1 asymmetry is restricted to below 2%.
