<p>CONTROL OF COLLIDING ION BEAMS A fusion reaction system is provided wherein ions from two sources are forced by passage through magnetic and electric fields to travel toward each other in opposite senses and directions under confinement to common helical paths at a common radius in a cylindrical reaction zone by radial electric fields. The ions are bunched along said helical paths to establish a plurality of concentrations of the ions located at spaced points along the paths with the points being the same for ions from both sources. Structure in the reaction zone is arranged for establishing local variations in the radial electric fields to produce the localized concentrations of ions as they traverse their helical paths. Further, means may be provided to velocity modulate the ion sources for producing standing waves along the reaction paths having velocity nodes located at points in the reaction zone where the localized concentrations occur. Variable voltage sources are connected to modulate the velocities of ions from the two sources for producing standing waves in the reaction zone having velocity nodes spaced the same as the spacing between the localized concentrations. Phase adjustment means provide for positioning the velocity nodes at the same points as the points at which the localized concentrations occur.</p> |
