Abstract
Filament sources of Rb+ ions were created using 90%Pt-10%Rh gauze coat ed with synthetic rubidium aluminosilicate compounds of various compos itions. The performance characteristics of these compounds as thermion ic emission sources of Rb+ ions based on total emission current and pu rity of ion emission as functions of time were studied and compared. I n addition, these characteristics were investigated of beta-eucryptite (Rb2O . Al2O3 . 2SiO2) and spodumene (Rb2O . Al2O3 . 4SiO2) Samples a t four different filament surface temperatures. It was concluded that the beta-eucryptite composition of rubidium aluminosilicate gives the most satisfactory results as a Rb+ ion emitter at a temperature of 110 0-degrees-C.
