To access, study and sustain burning plasmas on ITER with a high-fusion-power amplification factor, the use of external heating and current drive system plays an essential role. In particular, ITER will be equipped with two heating neutral beam injectors (with a provision of a third injector) and a neutral beam line for diagnostic purposes.
Achieving the requirements for the ITER neutral beam system in terms of power, energy, and pulse length is a major challenge that benefits from open exchange and collaboration. A cooperation agreement signed in 2020 between the ITER Organization, Consorzio RFX and EUROfusion formalizes the involvement of European experts in the ITER Neutral Beam Test Facility.

ITER is of key importance in the European research
At ITER Headquarters in late October, EUROfusion experts performing R&D for the ITER neutral beam injection system at Consorzio RFX and IPP Garching had the opportunity to present their research to the ITER Neutral Beam Advisory Committee and the ITER team.
