| Research Abstract |
High density negative ion source has been developed for the neutral beam injection system required for the future nuclear fusion system. A high density hydrogen plasma with more than 10(13)/cc was successfully obtained using the FET based RF power source.Ion beams were extracted from the source and measured using by the laser photo-detachment technique and a spectral apparatus.These results will provide important insights into the future neutral beam injection system.
