Density limits with different fuelling methods have been compared in HL-2A,i.e.directgas puffing and supersonic molecular beam injection(SMBI)from outer midplane,and divertorgas fuelling.The maximum densities for low current discharges are 3.4×l0~(19)m~(-3),4.3×l0~(-9)m~(-3)and 4.7×l0~(19)m~(-3)for the 3 kinds of fuelling methods.The corresponding density ratios to Greenwalddensity limit are 0.9,1.1,1.2,respectively.The behavior of density limit disruption isanalyzed as well.
Density limits with different fuelling methods have been compared in HL-2A, iedirectgas puffing and supersonic molecular beam injection (SMBI) from outer midplane, and divertorgas fuelling.The maximum densities for low current discharges are 3.4 × l0 ~ (19) m ~ (-3), 4.3 × 10 ~ (-9) m ~ (-3) and 4.7 × 10 ~ (19) m ~ (-3) for the 3 kinds of fuelling methods.The corresponding density ratios to Greenwald intensity are 0.9 , 1.1, 1.2, respectively. The behavior of density limit disruption isanalyzed as well.
