Abstract: A mathematical model for numerically simulating high current negative ion beam extraction and acceleration system has been established in order to assistantly design.The related computation method is described briefly.The electric and magnetic field conformation in the system is optimized and the initial optimized results of the 300 keV、5 electrodes negative ion beam system is given as well.

Key words: negative ion-based neutral beam injector, finite element method, numerical simulation
