THERMIONIC EMITTER MATERIALS RESEARCH PROGRAM

Abstract

Volume I of this report describes a program having the generation and interpretation of a reference set of thermionic converter output characteristics as its objective. Volume II is a compl te compendium of the reference set of data in its present form. In Volume I the experimental APPARATU AND TECHNIQUES ARE E CRIBED, AND THE EXPERIMENTAL MEASUREMENTS ARE ILLUSTRATED AND SUMMARIZED BY TYPICAL EXPERIMENTAL RESULTS. Emphasis was placed on suppressing perturbations by unknown variables, and on systematic survey of a broad range of parametric values. Emitter materials studied were niobium, tantalum, molybdenum, tungsten, rhenium and iridium. A method for systematic summary of the parameters observed to give maximum converter performance w s developed, and summary maps are presented for each material. Rhenium has exhibited the best over-all performance observed to date. (Author)
