Thin-film plasma liner formation and acceleration in a coaxial gun

The study of the formation and accelaration of cold plasma liners to obtain high stored/plasma energy coupling is presented. In particular, power amplification has been studied extensively with metal foils, gas puffs, and imploding wires. High energy coupling efficiency and power amplification can also be obtained with plasma liners derived from thin conductive films deposited on an insulating surface. The authors suggest that a repetitive system can be obtained with in-situ film deposition, and that deposition under high vacuum should reduce surface contamination effects such as precursor formation
