Abstract:This paper outlines the main features of a new high efficiency > 62%) high power (~20 MW D0) Neutral Beam concept based on pragmatic solutions suitable with the reactor requirements. The injector is modular (several beamlines in parallel) with independent ion sources referenced to the ground potential and gas neutralizers held at +1 MV. This topology leads to numerous simplifications; it overcomes the main issues of conventional NB systems, such as the complex 1MV electrical setup, the difficult ion sourc… Show more
