The results of numerical modeling of the ion-beam dynamics and the dynamics of secondary ions and electrons formed in the ion-optical system of a portable neutron generator are presented. The calculation was performed with the aid of the KARAT code in a two-dimensional flat geometry and axisymmetric geometry. To suppress back electrons, the magnetic field of permanent magnets was used in the flat geometry and a blocking electric field of an additional electrode was used in the axisymmetric geometry. The working configurations of both systems are shown.
