Target Fabrication of Opacity Experiments on Z for Weapons Science Applications

Opacity data are very important in high energy density physics experiments. Recent targets of alternating layers of either Al₂Te₃ or Mg/Sn with a CH tamper have been made for obtaining these data. These targets are geometrically simple in the half-moon configuration of the metal compound coating to the pure CH tamper but require stringent procedural requirements to fabricate to the purity requirements. These specific targets require mass ratios of elements that proved to be difficult to obtain while also having the requirement of being pinhole-free and oxygen-free.
