NEUTRAL PARTICLE BEAM INJECTOR BASED ON NEGATIVE IONS Russian patent published in 2017 - IPC G21K1/00 H05H3/02 

FIELD: physics.

SUBSTANCE: neutral particle beam injector based on the negative ions, containing an ion source, an accelerator and a converter in order to generate a beam of the neutral particles approximately of 5 MW with energy of approximately 0.50-1.0 MeV. Ions, generated by the ion source, are accelerated to the pre-injection at high energy accelarator by the electrostatic preaccelerator based on the multiaperture mesh that is used to draw the ion beams from the plasma and to accelerate to some fraction of the desired beam energy. A beam from the ion source passes through a pair of the deflecting magnets that provides the ability of the beam to move along the axis before entering the high energy accelerator. After acceleration to full energy, the beam enters the converter, wherein it is partially converted into a beam of the neutral particles. The remaining types of ions are separated by the magnet and sent to the electrostatic energy converters. The neutral particle beam passes through the check valve and enters the plasma chamber.

EFFECT: increased productivity of the neutral particle beam forming.
