In a fusion device tritium ions react with deuterium ions to produce helium atoms and fast neutrons, and the tritium and deuterium consumed in the reaction must be replaced to maintain steady state conditions. This paper presents a conceptual design of a neutral beam injector which aims to maximise the T0 injection into the machine whilst substantially reducing the amount of T2 that has to be cycled through the injector.
