Sufficient and reliable additional heating power and current drive of a Tokamak plasma are mandatory requirements to attain and to sustain fusion thermonuclear conditions in a reactor. Among the different systems to cope with these requirements the Neutral Beam Injectors are considered the “workhorse” for the operation of a Tokamak. From the present experiments in which positive ion are accelerated before neutralisation up to an energy lower than 200 keV for ITER and for DEMO it is required to inject particles based on negative ions that have to be accelerated up to 1 MeV before the neutralisation.
The power required to satisfy the scaling requested for a reactor increases form MW to tens of MW.
In the development of a system based on negative ions accelerated to the MeV scale a number of issues has to addressed to guarantee performances, efficiency, availability and reliability.
In the talk, starting from the present neutral beam systems based on acceleration of positive ions and from the actual status of development of systems based on negative ions, the main issues related to the development and the design of the ITER Neutral Beam Injector systems will be presented. Finally from the actual step of achievements and from the requirements for a fusion reactor like DEMO, the areas of development will be presented together with the pathway in which the R&D activities will have to be oriented in the next years.
