Ion beam formation by four-electrode ion optical system with slit finite length apertures is considered. Results of numerical simulations by two and three dimensional codes shown that accurate ion beam formation in slit aperture with semicircular ends can be provided. In experimental studies of beam formation in single slit ion optical system angular beam divergences of 0.53 deg. across the slit and 0.35 deg. along it were measured. Studied slit ion optical system will be used for ion beam formation in diagnostic neutral injector for large W-7X stellarator.
