Abstract: In Cadarche development on negative ion sources is being carried out on the KAMABOK III ion source on the MANTIS test bed. This is a model of the ion source designed for the neutral beam injectors of the International Thermonuclear Experimental Reactor (ITER). Its target performnce is to accelerate a D^- beam, with a current density of 200A/m² and <1 electron extracted per accelerated D^- ion, at a source pressure of 0.3 Pa. For ITER a continous ion beam must be assured for pulse lenghs of 1000 s, but beam of up to 3,600 s a also envisaged.
