Sigma Technologies proposes a unique patented process for the fabrication of high energy density (>10 J/cc) film capacitors for high efficiency plasma sparker application. Capacitor banks based on the proposed capacitors will have several attractive features s that include high energy density, light weight, low volume, and low costs. The proposed process is an improvement over a technology that was developed at Sigma, and which produced parts with energy densities of the order of 7J/cc. In Phase I, Sigma will design, fabricate, and test the highly efficient capacitor. In Phase II, Sigma will design and build a sparker module that is energized by the Phase I capacitors
