  2. Status of HL-2A Tokamak • Plasma parameters of HL-2A tokamak have been increased significantly with the improvement of the hardware • The stable and reproducible discharges with divertor configuration have been obtained by reliable feedback control and wall conditioning techniques. • BT: 2.8 T 2.7 T • IP: 480 kA 430 kA • Duration: 3.0 s • Plasma density: 6.0 x 1019 m-3 • Electron temperature: ~5 keV • Ion temperature: >1 keV • Fuelling system: GP, SMBI, PI • Heating sys.: ECRH, LHCD, NBI
