An Introduction to Ion Beam Etching - AZoM

The ion source generates a low temperature plasma with slow (cold) ions at an ion temperature less than 1eV, which can be extracted from the ion source through the grids with a well-defined energy. In a three grid system, specific potentials or voltages applied between the grids provide the driving force and focussing optic for the ions.
