Abstract

The article reports on the progress made by the ITER European Home Team in strong interaction with the ITER Joint Central Team and the Japan Atomic Energy Research Institute regarding several key aspects of The beam source for the ITER injectors: 1) Integration of the SINGAP accelerator into the ITER injector design. This is substantially simpler in concept than the multiaperture, multigap accelerator of the ITER NBI reference design that has the potential for significant cost savings and that avoids some of the weaknesses of the reference design such as the need for intermediate high voltage potentials from the high voltage power supply and pressurized gas installation. 2) High energy negative ion acceleration using a SINGAP accelerator. 3) Long pulse negative ion source operation in deuterium. 4) RF source development, which could reduce the scheduled maintenance of the ITE injectors, and simplify the transmission line and the auxiliary power supplies for the ion source.
