Target areal density (R) asymmetries in OMEGA direct-drive spherical implosions are studied. The rms variation hRi=hRi for low-mode-number structure is approximately proportional to the rms variation of on-target laser intensity hIi=hIi with an amplification factor of 1=2C r ÿ 1, where C r is the capsule convergence ratio. This result has critical implications for future work on the National Ignition Facility as well as OMEGA.
