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 ne=0.9e20/m^3 Density peaking=1.38 Calculated with ONETWO/ NUBEAM 切半径(cm) 400 450 500 550 600 650 700 Drive current (MA) 0.44 0.56 0.70 0.82 1.01 1.15 0.71 Driven current of 30MW NBI

4 ECCD for CFETR 140 GHz ECCD was selected, O1 mode
density profile is scaled from DIII-D 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 入射极向角 100 110 120 130 140 驱动电流(MA) 0.60 0.72 0.75 0.69 0.09 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 ?

8 谢谢
