Summary
The dissertation is devoted to investigation of efficiency manipulating of wide aperture intense ion beam of different elements of low and middle energy by high current plasma lens and effect of lens's aberrations on focus quality. In the thesis is shown what from parameters and as the focusing ability of such lens depends. It is shown, dependence of the lens static characteristics on a configuration of a magnetic field power lines, allocation of an external potential on electrodes and their amount, and also force of a passing ion beam current. The possibility of using of a spherical aberration for handle of the profile of a ion current density on the target in a specific place of an axes Z is shown. The formula of account of the radial profile of a potential in a thin plasma lens necessary for obtaining the homogeneous current density profile of ion beam on the target is offered. Possibility of a construction of a plasma lens without a spherical aberration experimentally is shown and the influence of a momentum aberration is investigated. Is shown as the momentum aberration effect on a wide aperture beam focusing in without the spherical aberration plasma lens and one uses possibility. The formula of account of a beam minimum radius with allowance for momentum aberration is offered. The small-scale oscillations that appearing in absence the spherical aberrations, of an irregular character, the integrated characteristics such dynamical aberration are investigated, and is shown, that the experimental results will be well agreed the outputs of the offered theory of their origin
Key words: high current plasma lens, ion beam of different elements, wide aperture ion beam, low energy ion beam, middle energy ion beam, intense ion beam, spherical aberration, momentum aberration, dynamical aberration.
