An update on ITER and the ITER Neutral Beam progress and development

ITER will have 2 Heating Neutral Beams (HNBs), with a possible third to be installed at a later date, and a Diagnostic Neutral Beam (DNB). The HNBs are designed to each provide 16.5 MW of power for ITER, as either 1 MeV D 0 (from 40 A D - ) or 0.87 MeV H 0 (from 46 A of H - ) for up to 3600 s. The DNB will provide a 100 kV (from 60 A of H - ) beam, for use with charge exchange spectroscopy at the edge of the ITER plasma. Following technical challenges, a large re-baselining effort has been performed for the whole ITER Program. The new strategy maintains the same timescale for achieving first nuclear operation, although with a shorter operational period before this. The new plan is presented, and the impact on Neutral Beam requirements is explained. The current state and focus of ITER NBI research and development is then discussed, including developments on the Magnetic Field Reduction System (MFRS) and the focal points of research for the ITER NBI Experiment Advisory Committee presented. The latest procurement status of the main components will also be shown, along with the developments on the ITER site related to the Neutral Beams.
