reportActive / Technical Report | Accession Number: ADA322452 | Open PDF

Abstract:

This paper presents the results of an investigation carried on for the following purposes 1 To determine the relative life of filaments when operated at low emission low temperatures as compared to those operated at high emission values. 2 To determine the nature of the dependence of life upon the initial diameter of the filament. 3 To determine the effect of varying concentrations of water vapor and air upon the life of the filaments. 4 To determine the relative life characteristics of tantalum as compared to tungsten.
