EVALUATION OF A MOLYBDENUM EMITTER, LOW VOLTAGE ARC THERMIONIC POWER CONVERTER
Abstract
Work was initiated to define and minimize the life limiting and degradation factors affecting the usefulness of the low-temperature cesium vapor converter. Basically, work is directed toward a life test evaluation of a state-of-theart planar cesium vapor thermionic converter. It is the goal to arrive at a technical specification for a state-of-the-art vapor converter utilizing a molybdenum cathode. Generally, the program will consist of four major activities: (1) fabrication and life test of the state-ofthe-art designs; (2) determination of the limiting factors; (3) the acquisition of operational data; and (4) the supply of vapor converters to ASD for further test and evaluation. The design of the life test equipment was completed and fabrication started. Six converters have been built and preliminary tests have been made on one device. A vacuum test station is being revised for taking operational and transient data. In order to expedite operational data acquisition, instantaneous viewing of the volt-ampere characteristics will be used. (Author)
