摘要：
Results are presented from experimental and theoretical studies of a space-charge lens for focusing a negative-ion beam. The space-charge field and the beam ion trajectories are numerically calculated for the lens used in the experiments. The results of calculations are compared with the experimental data. It is shown theoretically and experimentally that the proposed device allows one to achieve the main operating conditions of the space-charge lens: the inertial confinement of positive ions and the removal of electrons by an external electric field. The focusing field of the lens attains ∼100 V/cm, which provides a focal length of <20 cm.
