Description
In a future fusion reactor prototype under development at TAE Technologies, Inc., negative-ion-based neutral beams with a total power of 20 MW are used to sustain the p-B reaction in the plasma. The neutral beam system will comprise four injector modules, each capable of producing a 5 MW, 1 MeV steady-state neutral beam. The conceptual design of the injector module features a spatially separated ion source and an electrostatic accelerator. A photon or plasma neutralizer of the negative-ion beam will be employed to achieve an overall system energy efficiency of up to 80%. The distinct features of the negative-ion source, accelerator, and beam-duct elements are discussed. The ion source prototype is designed at about ½ scale of the final ion source to study options for the plasma box, which employs either microwave or hot-filament gas discharge, and for the grid system. It is intended to produce a 120 keV, 3 A negative-ion beam when operated in either the volume or surface negative-ion production regimes. The prototype’s design and the main goals of its studies are also briefly reviewed.
