Abstract:

An ion source generating ions by impact ionization of gas molecules is based on ionic focusing of the electron beam under a high vacuum. It contains an electron gun, an accelerating diaphragm, an electron and an ion collector. It differs by obtaining under a high vacuum without a magnetic field an intense ion current, which is focused by an electron beam pointed in the same direction. The ion collector is used for the purpose of effecting the necessary separation of ion and electron beams. The ion collector, which is at negative potential, is located behind the electron collector, and it also acts as an electrode to draw off the ions.
