Abstract

The invention provides an electron-impact ion source device having high brightness as compared to known Nier-type ion sources, while providing similar advantages in terms of flexibility of the generated ion species, for example. The ionization chamber of the device operates at high pressures and provides for a large number of interactions between the electron beam and the gas molecules.
