Applications<\/h2>\n\n\n\n

Ion sources are used at various fields in research and industry. These sources are becoming extensively applied not only in atomic, nuclear or particle physics, but in various technological fields such as high temperature chemical processes, semiconductor doping, etc.<\/p>\n<\/div>\n\n\n\n

SiC block heater technology<\/h2>\n\n\n\n

Instead of filament or electron bombardment heating – which suffer from plenty of limitations – we offer a newly developed block heater technology.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Emission source<\/h2>\n\n\n\n

Diameter: 18 mm @ 14 mm emission surface (can be increased). Thickness: 1.95 mm (double disc).<\/p>\n\n\n\n

A robust and stable setup which resists immediate power shutdown.<\/p>\n<\/div>\n\n\n\n

Emission material<\/h2>\n\n\n\n

Every alkali ion emission material is based on the following equation:<\/p>\n\n\n\n

X2<\/sub>O Al2<\/sub>O3<\/sub> 1.5 – 2SiO2<\/sub><\/p>\n\n\n\n

where X can be Li, Na, K, Rb or Cs as well.<\/p>\n\n\n\n

Improved method for emission surface formation: homogenize the constituent in tincture (solution) to reach molecular level mixing.<\/p>\n\n\n\n

Lithium – 3 mA\/cm2<\/sup>, Sodium – 3 mA\/cm2<\/sup>, Potassium: 2 mA\/cm2<\/sup>, Rubidium – 1.5 mA\/cm2<\/sup>, Caesium – 1 mA\/cm2<\/sup><\/p>\n<\/div>\n<\/div>\n\n\n\n
