The properties of multi-element axially symmetric electrostatic lenses as a possible matching device of linear accelerator injector are considered. The electrostatic lenses are more effective at small (up to 150 keV) injection energy which used for small sized linear accelerators of ions. The criteria for choosing the most suitable lens parameters are discussed. The results of five-electrode lens study are presented. The investigation was carried out by a numerical method. Preliminary modeling was carried out applying original programs developed at NSC KIPT in which numerical code based on the integral equations method for calculating the distribution of the field strength between the electrodes of a lens was used. For a detailed numerical study of the five-electrode electrostatic lens, was used a package of three-dimensional computer simulation of charged particle optics – IBSimu.
