General Atomics has supported the Los Alamos National Laboratory Defect Implosion Experiment series on OMEGA with the process design and production of banded, gas-tight, glow discharge polymer (GDP) capsules. Production of a banded target is a multistep, multidisciplinary process requiring micromachining for the band, GDP coating for the capsule wall, and aluminum sputter coating to seal the capsules for subsequent gas fill. Challenges included applying a micromachining technique to create the channel that would result in the desired band after coating, and modification of the aluminum coating process to create a permeation barrier that would cover the banded region to allow for gas filling. Information describing the fabrication steps and characterization techniques employed to analyze the banded targets will be presented.
