Executive Summary

We are studying the physical mechanisms and process parameters controlling the composition, density, thickness, grain structure, and surface morphology of film coatings using the high-power pulsed sputter deposition process. The basic understanding of this process will impact a broad range of industrial applications, including laser targets for future inertial-confinement fusion and high-energy-density campaigns.
