Patent abstract

The invention relates to an electron impact gas ion with high brightness and low energy spread. This high brightness is achieved by injecting electrons in a small ionization volume (from less than 1 μm to several tens of micrometers in size) from one side and extracting ions from the other. The electrons injected are produced by a high brightness electron source, such as a field emitter or a Schottky emitter.
