  • Electron beam excited ion irradiation apparatus
    Patent number: 5326981
    Abstract: In an electron beam excited ion irradiation apparatus which irradiates ions to a material, an electrical discharge changes an inert gas into a plasma. Electrons are drawn from this plasma and are made into electron beams. The electron beams are passed through an active gas to create ion. When the ion is irradiated to a material, electron components of the electron beams, which are irradiated vertically to a surface of the material are changed their irradiation direction. Control of the range of electron beam irradiation is performed by a magnetic filed formed so as to surround the ion beams.
