1. In a fusion reaction system where ions from two sources spiral toward each other on common axis while rotating in opposite senses in orbital paths of common radii in an annular reaction zone of circular symmetry at any given cross section perpendicular to the axis of said paths and bounded by spaced apart outer and inner coaxial electrode walls for promoting collisions of ions in one beam with ions in the other beam, the improvement comprising:
- (a) electrostatic field means for causing said ions normally to orbit at said radii in said zone; and
(b) structure for establishing electric focusing fields operable in the absence of any effective magnetic fields within said reaction zone to force ions traversing scatter paths back into said orbital paths.

Abstract
This invention relates to the control of ions orbiting in a cylindrical reaction space and more particularly to attenuation of instabilities in two counterflow streams of ions to focus the ions of both streams into a predetermined orbital reaction zone.
