  1. CFETR电流驱动的初步讨论 李国强 任启龙 刘素梅 宋云涛 中科院等离子体物理研究所

  2. 中性束切向注入 • 目前的窗口应该可以实现中性束切向注入 • ITER NBI aperture size (58cm,136cm) • May vertically tilt to drive off-axis current

  3. The driven current of different injection angle • 磁轴高度上水平入射 • 1 MeV NNBI, 30MW • density profile is scaled from DIII-D 136345. • ne=0.9e20/m^3 • Density peaking=1.38 • Calculated with ONETWO/ NUBEAM Driven current of 30MW NBI

  4. ECCD for CFETR 140G 共振面 170G 共振面 • 140 GHz ECCD was selected, O1 mode • density profile is scaled from DIII-D 136345 • Calculated with ONETWO/TORAY-GA • For ITER, the CQL3D results are about 1.2 times of TORAY-GA • 弱场侧斜上方入射，扫描入射角度 • 需要更多的扫描计算 30MW ECCD, 环向角230度

  5. ECCD calculation on ITER

  6. LHCD • LHCD efficiency becomes lower with the density increase, but still higher than NBCD and ECCD • But the driven current cannot access the core region FDF, 30MW ITER, 30MW, ne=7.25e19/m^3

  7. Discussion • Lower density is beneficial for CD • How to balance the density and fusion power? • The combination of Heating/CD ?
