    摘要: A non-resonance photo-neutralizer for negative ion-based neutral beam injectors. The non-resonance photo-neutralizer utilizes a nonresonant photon accumulation, wherein the path of a photon becomes tangled and trapped in a certain space region, i.e., the photon trap. The trap is preferably formed by two smooth mirror surfaces facing each other with at least one of the mirrors being concave. In its simplest form, the trap is elliptical. A confinement region is a region near a family of normals, which are common to both mirror surfaces. The photons with a sufficiently small angle of deviation from the nearest common normal are confined. Depending on specific conditions, the shape of the mirror surface may be one of spherical, elliptical, cylindrical, or toroidal geometry, or a combination thereof.

    摘要: An improved ion beam neutralizer (22) is provided for neutralizing the electrical charge of an ion beam (28) output from an extraction aperture (50). The neutralizer comprises a source of water (52); a vaporizer (54) connected to the source of water; a mass flow controller (56) connected to the vaporizer; and an inlet (60) connected to the mass flow controller. The vaporizer (54) converts water from the source (52) from a liquid state to a vapor state. The mass flow controller (56) receives water vapor from the vaporizer (54) and meters the volume of water vapor output by a mass flow controller outlet (66). The inlet (60) is provided with an injection port (68) located proximate the ion beam extraction aperture (50) and receives the metered volume from the outlet (66). The injection port (68) is positioned near the extraction aperture so that the ion beam and the water vapor interact to neutralize the ion beam. The improved ion beam neutralizer (22) is especially effective in low energy (less than ten kilo-electron volts (10 KeV)) beam applications.
