The NIO1 experiment is a compact and modular negative ion source built at Consorzio RFX, Padua, with the aim to investigate the optimal configuration for a negative ion source of the type needed for the nuclear fusion experiment ITER. Negative ions, produced in a cold plasma, are extracted from it by an intense electric field, generated by applying a potential of some kilovolts to an electrode called "extraction grid" (EG). This electrode has permanent magnets in it, needed to deflect the electrons that are unavoidably extracted from the source. A new EG, completely redesigned with respect to the original one has been recently installed on NIO1. The aim of this thesis consists in following the installation of such electrode, contributing to...
