Abstract

The use of rf ion sources in neutral beam injection systems offers reduced maintenance and cost due to the absence of filaments. For the first time high-power rf positive ions sources have been put in operation recently in a real NBI system on a tokamak. The performance of the system is equivalent to that of a conventional one with arc discharge sources. Due to the relevance for the ITER, rf sources are also being investigated in context with negative ions: 8.5 mA/cm(2). H- have been achieved so far in a non-optimized version
