Abstract
An ion beam generator includes: an ion generating section for generating ions and where the material to be ionized is introduced; a gas discharge device for exciting the material to be ionized to a low excited state; a light source for introducing a light into the ion generating section, which light has a wavelength such that it excites the material to be ionized to an intermediate state from the low excited state of the material by a resonance excitation; and the specific material to be taken out as an ion beam being selectively ionized through the intermediate state.
