A comprehensive set of R&D activities has been carried out at Consorzio RFX regarding the construction of the grids for the ITER Neutral Beam Injectors, in order to validate the proposed manufacturing methodologies, to further develop the details of the engineering design, and to adapt existing production techniques to the specific case. In the framework of this R&D program, two Multi Channel...
The MITICA experiment will be the full scale prototype of the neutral beam injectors to be installed on the ITER device. Its aim is to demonstrate and optimise a 16 MW neutral beam power, obtained by neutralization of a 56 A deuterium negative ion beam D− accelerated to an energy of 1 MeV. Since the current expected density available at the source is around 300 A/m2, a large extraction area is needed...
The SPIDER experiment's main goal is to test the extraction of negative ions from an ITER-size ion source. It is designed to extract 1 280 negative ion beamlets and accelerate them up to a 100 kV potential. The negative ion beam at exit and the operating parameters will be carefully measured and optimized in order to match the ITER requirements for the Neutral Beam Injector (NBI) ion sources. Inside...
