Abstract：
An ion source for HL-2A Neutral Beam Injection (NBI) was operated successfully in March 2007, in Southwestern Institute of Physics. A bucket source type and three-grid-system are used in this new ion source design. The filament current of 1100A, filament voltage of 12V, arc current of 1050A, arc voltage of 120V, highest plasmas density of 2.5×10¹²/cm³, extracted ion beam density of 0.44A/cm², plasma density uniformity better than 5% in the area close to the first grid, duration of 2s, for this new source, have been achieved. The conceptual design, mechanical design and experiment result for the ion source are presented briefly in this paper.
