摘要：

This paper we report the first results on a prototype negative ion source for LHD-NBI. The ion source with a multi-cusp configuration consists of the external magnetic filter and has an inner volume of 140 cm in height x 35 cm in width x 25 cm in depth. Two cesium lines are installed to seed cesium vapor into are plasma for enhancement of H- current. The H- ion beam was extracted from an area of 120 cm x 25 cm and was accelerated via single-stage accelerator. An H- current of about 4 A with the energy of 73 keV was obtained at the are power of 250 kW for a duration of 0.3 sec.
