摘要：
The injector ion source [1] is based on an arc-discharge plasma box. The plasma emitter is produced by a 1 kA arc discharge in deuterium. A multipole magnetic field produced with permanent magnets at the periphery of the plasma box is used to increase its efficiency and improve homogeneity of the plasma emitter. The ion beam is extracted by a 4-electrodes ion optical system (IOS). Initial beam diameter is 200 mm. The grids of the IOS have a spherical curvature for geometrical focusing of the beam. The optimal IOS geometry and grid potentials were found by means of numerical simulation to provide precise bean? formation. The measured angular divergence of the beam is 0.025 rad which corresponds to a 4.7 cm Gaussian radius of the beam profile measured at focal point.
