This work considers Coulomb forces acting on a charged point particle located between the two coaxial, likely charged rings laying at some distance between one another. Conditions under which the charged particle, while being affected by Coulomb repulsion forces of charges of the rings, localises in the space between the rings and moves along a closed trajectory around the axis of charged rings, not leaving the space between them, were determined. Also, conditions at which a controlled ejection of the charged particle from its localisation zone (or the capability to control the kinetic energy and direction of ejection of the particle) is possible, were determined. Based on the obtained results, we conclude that the considered method of localisation and controlled ejection of charged particles is applicable both in experiments on the nuclear synthesis in swarms of localised positively charged particles and for the formation of beams of likely charged particles with the given velocity of motion relatively to the charged rings.
