Abstract: HL-2A Tokamak has been put into operation in Southwestern Institute of Physics since 2002. It is characterized by the first divertor and first elongated plasma cross-section in China. The coils of HL-2A are made up of copper conductor to enhance the flexibility and accessibility to plasma. All of the poloidal-field coils are located inside the toroidal-field coils. The multiple coils located inside the vacuum vessel are able to establish a double-null configuration. HL-2A has been equipped with 30 sets of advanced diagnostic systems and 4 MW auxiliary heating systems. The fueling system and technology of HL-2A keep being continuously developed. With the constructions for above systems and progress on the integrated technologies on the plasma discharge control, HL-2A has achieved H-mode plasma successfully. The experimental progresses on HL-2A are of significance for the advanced Tokamak plasma experiments and studies on the science, technique and engineering issues related to ITER and a fusion reactor, make HL-2A active for fusion plasma research and contribute to the international Tokamak activities.
