Technical Paper / Eighteenth Target Fabrication Specialists' Meeting
A specialized magnetron co-sputtering process to fabricate a 0.3- to 0.6-m-thick sputtered gold-boron (AuB) liner in inertial confinement hohlraums (inertial confinement fusion) to the specified concentration of 80% Au and 20% B has been developed at General Atomics. The AuB layer concentration in atomic percent is characterized by witness pieces using depth-profiling Auger electron spectroscopy. The results of the initial research and development effort and the yield in pilot production of AuB-lined gold hohlraums are presented.
