Some preliminary experiments have been performed to determine the effect of mandrel geometry and plating both composition on the thickness uniformity of gold and copper electroformed hohlraums. It was observed that for gold plating, the edge radius has a dramatic influence on uniformity in a direction opposite that expected (i.e., uniformity worsened with larger radius) and that extension of the front small-diameter cylinder gave a slight improvement in hohlraum symmetry. In the case of copper plating it was found that, as expected, reduced metal concentration improved uniformity, however, it was also found that the selection of additives has an even more pronounced effect.
