Development of a High Energy Density Capacitor for Plasma Thrusters.
Abstract
This report presents the results of a technology program directed towards the development of a long-life, high-energy density capacitor for application in spacecraft. The capacitor has low inductance (approximately 20 nH) and an energy density up to 40 J/lb. Voltage vs. life curves are shown which indicate this capacitor will withstand over 10 to the 7th power discharges when operated at rated voltage of 2.2 kV. Materials were employed in this capacitor which should render it resistant to damage from radiation. To attain radiation resistance and high-energy density, kraft tissue was successfully excluded from the winding which is composed principally of K-F polymer and aluminum foil. Various impregnants were tested and the most successful was silicone oil. (Author)
