 | Efforts included emitter and collector work function measurements of three converters which are on life-test. No appreciable change in either the emitter or the collector work function was found with time of operation. Metallurgical and chemical analysis was performed on one converter (403-series) that failed after 879 cycles of operation. Mass spectrometric analysis was conducted of the gases evolved during outgassing of one converter, (403-series). Two converters of the 402-series ... |

| This report covers work on thermionic converters, generators, and thermionic converter additives. Efforts included emitter work function measurements of seven converters which are on life-test and collector work function measurements of these converters. The work function measurements were taken at about 1500-hour intervals on the steady-state life-test converters and about 1000 cycle intervals on the cyclic converters. No appreciable change in the work function of either the emitter or the ... |

| The two major goals of this program are: (1) to develop a clear understading of the factors which affect the life and performance of thermionic converters through the use of adequate diagnostic tools, and (2) to acquire the technology and techniques necessary to design and fabricate experimental converters having long life and high power output on a repeatable and predictable basis. Efforts during this quarter included the final assembly of ... |
