Diagnostics for negative ion source NIO1

The development of Neutral Beam Injectors (NBI) as auxiliary heating systems for ITER, the experimental reactor that will be realized in Cadarache (France), is a fundamental topic of the fusion science research in the last decades. For this purposes much effort is being to improve the understanding of the physics of negative ion beams and sources. This thesis deals with the negative ion source NIO1, developed at Consorzio RFX in collaboration with INFN laboratories in Legnaro (Padova), in particular concerning the design, development and setup of some of the diagnostics for the first operation of the NIO1 source.
