Abstract: Until quite recently, the neutral beams used in magnetic fusion research, material processing, etching, sterilisation and other applications were all formed from positive ions. Neutral beams require energies well beyond that accessible with positive ions. Negative-ion-based neutral beams have been developed in recent years. However, beam currents achieved so far are significantly less than that produced quite routinely by positive ion sources. A negative ion-based beam injector comprises an ion source adapted to produce a negative ion beam, wherein the ion source includes a plasma box with internal walls maintainable at elevated temperatures of about 150-200° C, a pre-accelerator, a high energy accelerator interconnected to and spaced apart from the pre-accelerator and ion source by a transition zone interposing the pre-accelerator and the high energy accelerator, wherein the transition zone comprises a pair of deflecting magnets that enable a beam from the pre-accelerator to shift off axis from an axis of the pre-accelerator and onto a non-coaxial axis of the accelerator before entering the high energy accelerator, wherein the pre-accelerator include one or more positively biased electrodes to repel back streaming positive ions.

Abstract: A negative ion-based beam injector comprises an ion source configured to produce a negative ion beam, the ion source including a pre-accelerator having external magnets to deflect co-extracted electrons in an ion extraction and pre-acceleration region, wherein the pre-accelerator comprises an electrostatic grid having a plurality of electrodes, wherein at least one of the plurality of electrodes is positively biased to repel back streaming positive ions. The injector further comprises an accelerator spaced apart from the pre-accelerator. By using external magnets rather than magnets embedded into the grid body, enables the magnets to be heated up to elevated temperatures. Previous designs tend to utilize magnets embedded into the grid body, which tends to cause a significant reduction in extracted beam current and prevent elevated temperature operation as well as appropriate heating/cooling performance.

Abstract: A negative ion-based neutral beam injector comprising a negative ion source, accelerator and neutralizer to produce about a 5 MW neutral beam with energy of about 0.50 to 1.0 MeV. The ions produced by the ion source are pre-accelerated before injection into a high energy accelerator by an electrostatic multi-aperture grid pre-accelerator, which is used to extract ion beams from the plasma and accelerate to some fraction of the required beam energy. The beam from the ion source passes through a pair of deflecting magnets, which enable the beam to shift off axis before entering the high energy accelerator. After acceleration to full energy, the beam enters the neutralizer where it is partially converted into a neutral beam. The remaining ion species are separated by a magnet and directed into electrostatic energy converters. The neutral beam passes through a gate valve and enters a plasma chamber.

Abstract: 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.
