Available in PDF, EPUB and Kindle. Book excerpt: Several emitter materials, tantalum, tungsten and rhenium, and two emitter geometries, planar and excess area were evaluated in a flexible laboratory thermionic converter design. Results are reported from six converters that were tested for a total of 1070 hr. Experimental results from the excess area emitter converters did not exhibit the current enhancement observed in multicapillary and slotted emitter converters developed on a previous Air Force contract. While the electron currents in the passive mode at relatively low cesium pressure were in qualitative agreement with theory, the actual current densities obtained were not high enough to produce practical power densities at high output voltage. The method of emitter fabrication which used a niobium braze material appears to be a primary reason for the low performance.

This book was released on 1964 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effort was continued to improve performance and increase the reliability of thermionic energy converters for space applications. The particular objectives include optimization of geometry and ceramic insulation between emitters and heat source. This work will include the development of a thermionic generator module to develop 3.0 volts of potential from a liquid metal heat source. The overall concept of the 3-volt generator has been established. Before final design and fabrication of the generator, the more difficult problems are being solved by fabricating and testing prototype 3-converter modules. During this period, four 3-converter modules were assembled. A number of subassemblies were successfully tested and techniques for assembling a series of converters within a single envelope were perfected. A method of bonding the center heat source tubing has been tentatively selected and materials for detailed evaluation of the method have been ordered. Life testing of one Type A1198B converter was concluded after 1010 hours. Another converter of this type has since completed 600 hours of a life test with a constant output of 46 watts. (Author).

This book was released on 1964 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: A thermionic energy converter based on a coaxial diode configuration was used to obtain information relative to problems associated with instrumenting and heating a large-scale converter and to determine certain thermal and thermionic characteristics. The cylindrical tungsten cathode, having an emitting area of 73.7 square centimeters, was operated at temperatures in the range 1200° to 2000° K. Diode thermal characteristics such as temperature gradients, temperature ratios, heat-flow distributions, and thermal emissivities were studied. Thermionic characteristics were determined in both a vacuum and a cesium vapor atmosphere. The investigation defined problems associated with thermal gradients on emitting areas, interelectrode resistive leakage caused by vapor deposition, determination of heat-transfer properties, and measurement of cathode emission properties.
