| English abstract | To improve the beam brightness produced in the 12 MeV Van de Graaff linear accelerator at Instituto Nacional de Investigaciones Nucleares we studied the beam generation inside the ion source. New 3D particle tracking simulations have been compared with measurements, and the agreement is better than using the traditional approach of only accounting for the primary beam. Among the results, it was observed that the main limit in the generation of intense beams is the suppression of the Cesium production due to space charge on the surface of the ionizers. In addition, the beam dynamics variation due to the erosion of the target inside the cathode has been determined. All these results allow us to find the optimal combinations for beam extraction |
