Abstract : Methods of increasing the yield of an ion source for an electromagnetic separator on the basis of selecting the optimum geometry for the ion-optical system are discussed. Ion beam dispersion in the plane of the trajectory at the output was studied as a function of the main characteristics of the source. Sources used for the separation of stable isotopes over a wide range of isotope masses were analyzed and the effect of uncompensated positive space charge in the beam was evaluated. A graph is given showing current density as a function of ion mass for various ion-optical geometries. The results of the research were used to design a separator for lead ions that have a PB current density of approx. 50 ma/sq cm, representing an improvement over previous ion-optical systems of one order of magnitude.
