Abstract
Abstract An ion beam generator having an ion generating section for generating ions where the material to be ionized is introduced and a light source for introducing a light into the ion generating sections. This light has a wavelength such that it excites the material to be ionized to the intermediate state from the ground state of the material by a resonance excitation. The specific material to be taken out as an ion beam is selectively ionized through the intermediate state.
