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.

针对未来核聚变系统所需的中性束注入系统，研制了高密度负离子源。利用基于FET的射频电源，成功地获得了大于10(13)/cc的高密度氢等离子体。从光源中提取离子束，利用激光光分离技术和光谱仪对离子束进行测量。这些结果将为未来的中性束注入系统提供重要的见解。
