Abstract : Considerable progress was made on the five-fold research projects of Phase I. In evaluating current design, an improved metallizing technique was developed for stronger ceramic-to-metal seals. In the area of performance improvement, cesium purification methods were investigated and positive contributions obtained. Testing and evaluation of the heat pipe continued with particular emphasis on problems inherent to the lithium working fluid. Evaluation of aluminum oxide as an emitter insulation probed into the merits ofincreased layer thickness. Converter-Heat Pipe Assemblies 4 and 5 received performance testing; thereby yielding valuable data; while fabrication of Converter A-1198C, No. 6, was completed and the unit readied for life testing.
