ENERGETIC NEUTRAL PARTICLE INJECTION SYSTEM FOR CONTROLLED FUSION REACTOR

摘要

System including an ion source, particle accelerator and neutralizer cell for producing an energetic neutral particle beam which is directed into the containment zone of a controlled fusion reactor. Said beam includes a significant proportion of ionized particles and a proportion of the energetic neutrals are not trapped in the containment zone. Magnetic field means are used to deflect the ionized particles from the neutral particle beam and an ionizer cell is used to ionize neutral particles escaping from said containment zone. Means including spaced arrays of grid structures are arranged to deflect electrons and collect the deflected and reionized particles in a manner adapted to collect and convert the kinetic energy of the particles into electrical energy.
