A pair of axial gold disks is used to reduce the capsule view of the two laser-entrance-holes in hohlraums irradiated by the Nova laser [E. M. Campbell {ital et} {ital al}., Rev. Sci. Instrum. {bold 57}, 2101 (1986)]. By varying the disk radii a novel means of tuning the x-ray drive flux asymmetry is provided. Predicted implosion asymmetry is experimentally validated over a wide range of disk radii. Although simulations suggest increased x-ray drive onto the capsule in the presence of gold disks, neutron-based diagnostics are inconclusive in this regard. {copyright} {ital 1996 American Institute of Physics.}
