DOE/JPL advanced thermionic technology program. Progress report No. 38, February-March 1979

Progress on DOE tasks is reported including (1) surface and plasma investigations (surface characterization chamber experiments, spectroscopic plasma measurements, and converter theory), (2) low temperature converter development (tungsten emitter, lanthanum hexaboride collector and tungsten emitter, tungsten oxide collector), and (3) component hardware development. JPL tasks reported include high-temperature converter evaluation, advanced converter studies, and correlation of design interfaces. (WHK
