dc.description.abstractFilament sources of Rb+ ions were created using 90% Pt-10% Rh gauze coated with synthetic rubidium aluminosilicate compounds of various compositions. The performance characteristics of these compounds as thermionic emission sources of Rb+ ions based on total emission current and purity of ion emission as functions of time were studied and compared. In addition, these characteristics were investigated of β-eucryptite (Rb2O·Al2O3·2SiO2) and spodumene (Rb2O·Al2O3·4SiO2) samples at four different filament surface temperatures. It was concluded that the β-eucryptite composition of rubidium aluminosilicate gives the most satisfactory results as a Rb+ ion emitter at a temperature of 1100°C. © 1994.
