Abstract

Field emission based ionization sources are provided, with the emitter (305) being a carbon nanotube field emitter. Such emitters can replace Ni-63 beta emitters. Ionization of a gas (308) that is flowed through the gap (310) between the emitter plates (301, 302) is performed by electron capture of the flow of electrons by the molecules in the gas (308).
