A beam of ions in the fonn of "canal rays" was first observed in
1886 by E. Goldstein. The first ion source was invented by J. J.
Thomson in 1910. This ion source became the basis for the first
widespread application of ion sources in mass spectrographs and
mass spectrometers. The second important application of ion sources
is ion accelerators, which since the beginning of the 1930s have
been employed in research on nuclear reactions and are now used in
industry and medicine. A third application of ion sources is in
systems for isotope separation and re search on the interaction of
atomic particles with solids (1940s). The result of this research
and development is the use of ion sources in semiconductor doping,
decontamination of surfaces, and micromachining of surfaces (1960s
and' 1970s), which is a fourth area of applications for ion
sources. The heating of plasmas in magnetic confinement devices to
thennonuclear temperatures (100-1000 MK) with the aid of megawatt
beams of hydrogen and deuterium ions and atoms has become a fifth
promising area of application for ion sources which can produce ion
beams with steady-state currents of up to 100 A. Finally,
experimental and industrial research are under way on the alloying
of metals and the fabrication of coatings which greatly improve the
physical and chemical properties of metals. These coatings can
increase the hardness, high temperature corrosion resistance, and
wear resistance of metals, and can enhance or reduce friction,
etc."
