Abstract :
The plasma lens in which the magnetic surfaces are equipotentials of an electrical field is considered. The results of simulation of high-density, large-aperture ion beam focusing are given in view of their longitudinal, radial, and azimuthal motion. Geometrical and moment aberrations were taken into account. Optimization of lens fields was realized; discrete distribution of the lens electrical potential was studied.
