THE DEVELOPMENT OF A LOW TEMPERATURE VAPOR FILLED THERMIONIC CONVERTER
Abstract
The development of a low-temperature, plasma, thermionic converter is described. The converter uses a third electrode to ionize plasma so as to neutralize the space charge. The lower temperature thus achieved should significantly prolong the life of the converter and contribute to the development of a more reliable power supply for space application. Research was directed toward optimizing geometry and operating characteristics and investigating the effects of temperature and pressure, starting pulse, magnetic fields, and operation in both series and parallel circuitry. Materials were investigated to achieve practical electrodes by determining compatibility of material, atmospheric corrosion, and gas permeation. Converters were fabricated, evaluated, and life tested with the parameters optimized by the test program.
