Description
The ITER tokamak will rely on negative ion–based Neutral Beam Injectors (NBIs) for auxiliary heating and current drive, as well as for high resolution spectroscopic diagnostics of burning plasmas. The heating system comprises two, with an option for a third, Neutral Beam Injectors capable of delivering 16.5 MW of MeV class neutral hydrogen or deuterium atoms, while a dedicated Diagnostic Neutral Beam will operate at 100 keV to support advanced plasma measurements. Following the 2024 ITER re baseline, the development plan for these systems has been refined to align with the updated project schedule and integration strategy.
Manufacturing of the captive components is progressing, with installation of the injectors’ vessels, high voltage power supplies, and the magnetic field compensation system planned ahead of ITER’s first experimental phase and advancing with strong support from the Domestic Agencies. Full injector assembly and installation will follow the first operation phase, ensuring readiness for ITER’s nuclear campaigns. In parallel, design validation and performance optimization continue through dedicated modelling activities and within the long term experimental program at the Neutral Beam Test Facility, recently updated and aligned with ITER needs.
This contribution will present the current status of the ITER NBI program, highlight the technical progress achieved since the re baseline, and outline the remaining challenges and planned activities leading to injector deployment for ITER’s fusion operation campaigns.
